Under certain circumstances, when I right-click in the empty space in
Windows Explorer, in any folder or subfolder beneath any "Libraries"
folder (e.g. my "Documents"), the "Bash Prompt Here" option is not
shown in the context menu.
Option is *not shown* under these circumstances:
1. Browse to the folder/subfolder via the Libraries tree on the left
pane in Windows Explorer. (Including after drilling down via the right
side by double clicking.)
2. After #1, even if I copy the path from the explorer bar, and paste
it back in to the same, and press Enter.
However, the option *is* shown under the following circumstances:
3. Folders/subfolders not under Libraries.
4. Browse to the folder from the absolute path. (i.e. Via drive
letter, folder, subfolder...not via Libraries.)
5. Right-click on the folders/subfolders themselves (not on empty
space inside them), even if browing to them via Libraries.
6. Browse to folder under Libraries in Explorer via the Libraries
listed on the left. Copy the path from the location bar, paste it into
a *new explorer window*. Right click in the empty space within the
folder.
`which chere` tells me it's version 1.4. I'm running Cygwin x64 on
Win7 x64 w/ SP1. Redacted cygcheck.out attached.

"Libraries", despite the looks in Explorer, isn't a folder and not a
place you can set the current directory to.

The folders I'm talking about *are* located on the filesystem, so you
certainly can cd to them.
This is evidenced by the path shown when you click on the location
bar. And also, as described, it works when you click on the folders
themselves (even if you browse to them via Libraries), but doesn't
work when you click the empty space from inside the same folders.
This should work.

Bash outputs no value when using it's built in method of printing an
"epoch" timestamp.
BashCommandLine#: printf '%(%s)T' -1
I've verified the same behavior with others on IRC.

Check. This was in your patch so it's upstream now.

Email paste may have converted tabs to spaces - need to work out how to
email inline text attachments without tab expansion in tbird - paste on
gmane (below) seems to retain tabs - may try that in future.

Thanks - total brain fart - Doh! Interesting that gcc -Wall -Wextra did not
catch this - used to be reliable warning about conditionally uninitialized

No worries, I applied your other patch since it also cleaned up some
whitespaces and, for some reason, the below patch didn't apply cleanly.
There was just one problem:

This setting the offset to 0 is necessary, but commented out. Typo?
I fixed this before committing the patch.

Hi Corinna,
Just sent third try to this list, -patches, and yourself:

Tried to download and build from source tarball, then cygport, then
local source file, but some unobvious build prereqs missing in all
cases, as reported by ld. Finally just diffed local source against
distro and posted from gmane, with attempted fixups in the post.

Sorry, not using git yet, as I am set up with hg on BitBucket
- AIUI the output is close enough the attached should work okay.

+FUNCTION
+<<strftime>>---convert date and time to a formatted string
+
+INDEX
+ strftime
+
+ANSI_SYNOPSIS
+ #include <time.h>
+ size_t strftime(char *restrict <[s]>, size_t <[maxsize]>,
+ const char *restrict <[format]>,
+ const struct tm *restrict <[timp]>);
+
+TRAD_SYNOPSIS
+ #include <time.h>
+ size_t strftime(<[s]>, <[maxsize]>, <[format]>, <[timp]>)
+ char *<[s]>;
+ size_t <[maxsize]>;
+ char *<[format]>;
+ struct tm *<[timp]>;
+
+DESCRIPTION
+<<strftime>> converts a <<struct tm>> representation of the time (at
+<[timp]>) into a null-terminated string, starting at <[s]> and occupying
+no more than <[maxsize]> characters.
+
+You control the format of the output using the string at <[format]>.
+<<*<[format]>>> can contain two kinds of specifications: text to be
+copied literally into the formatted string, and time conversion
+specifications. Time conversion specifications are two- and
+three-character sequences beginning with `<<%>>' (use `<<%%>>' to
+include a percent sign in the output). Each defined conversion
+specification selects only the specified field(s) of calendar time
+data from <<*<[timp]>>>, and converts it to a string in one of the
+following ways:
+
+o+
+o %a
+The abbreviated weekday name according to the current locale. [tm_wday]
+
+o %A
+The full weekday name according to the current locale.
+In the default "C" locale, one of `<<Sunday>>', `<<Monday>>', `<<Tuesday>>',
+`<<Wednesday>>', `<<Thursday>>', `<<Friday>>', `<<Saturday>>'. [tm_wday]
+
+o %b
+The abbreviated month name according to the current locale. [tm_mon]
+
+o %B
+The full month name according to the current locale.
+In the default "C" locale, one of `<<January>>', `<<February>>',
+`<<March>>', `<<April>>', `<<May>>', `<<June>>', `<<July>>',
+`<<August>>', `<<September>>', `<<October>>', `<<November>>',
+`<<December>>'. [tm_mon]
+
+o %c
+The preferred date and time representation for the current locale.
+[tm_sec, tm_min, tm_hour, tm_mday, tm_mon, tm_year, tm_wday]
+
+o %C
+The century, that is, the year divided by 100 then truncated. For
+4-digit years, the result is zero-padded and exactly two characters;
+but for other years, there may a negative sign or more digits. In
+this way, `<<%C%y>>' is equivalent to `<<%Y>>'. [tm_year]
+
+o %d
+The day of the month, formatted with two digits (from `<<01>>' to
+`<<31>>'). [tm_mday]
+
+o %D
+A string representing the date, in the form `<<"%m/%d/%y">>'.
+[tm_mday, tm_mon, tm_year]
+
+o %e
+The day of the month, formatted with leading space if single digit
+(from `<<1>>' to `<<31>>'). [tm_mday]
+
+o %E<<x>>
+In some locales, the E modifier selects alternative representations of
+certain modifiers <<x>>. In newlib, it is ignored, and treated as %<<x>>.
+
+o %F
+A string representing the ISO 8601:2000 date format, in the form
+`<<"%Y-%m-%d">>'. [tm_mday, tm_mon, tm_year]
+
+o %g
+The last two digits of the week-based year, see specifier %G (from
+`<<00>>' to `<<99>>'). [tm_year, tm_wday, tm_yday]
+
+o %G
+The week-based year. In the ISO 8601:2000 calendar, week 1 of the year
+includes January 4th, and begin on Mondays. Therefore, if January 1st,
+2nd, or 3rd falls on a Sunday, that day and earlier belong to the last
+week of the previous year; and if December 29th, 30th, or 31st falls
+on Monday, that day and later belong to week 1 of the next year. For
+consistency with %Y, it always has at least four characters.
+Example: "%G" for Saturday 2nd January 1999 gives "1998", and for
+Tuesday 30th December 1997 gives "1998". [tm_year, tm_wday, tm_yday]
+
+o %h
+Synonym for "%b". [tm_mon]
+
+o %H
+The hour (on a 24-hour clock), formatted with two digits (from
+`<<00>>' to `<<23>>'). [tm_hour]
+
+o %I
+The hour (on a 12-hour clock), formatted with two digits (from
+`<<01>>' to `<<12>>'). [tm_hour]
+
+o %j
+The count of days in the year, formatted with three digits
+(from `<<001>>' to `<<366>>'). [tm_yday]
+
+o %k
+The hour (on a 24-hour clock), formatted with leading space if single
+digit (from `<<0>>' to `<<23>>'). Non-POSIX extension (c.p. %I). [tm_hour]
+
+o %l
+The hour (on a 12-hour clock), formatted with leading space if single
+digit (from `<<1>>' to `<<12>>'). Non-POSIX extension (c.p. %H). [tm_hour]
+
+o %m
+The month number, formatted with two digits (from `<<01>>' to `<<12>>').
+[tm_mon]
+
+o %M
+The minute, formatted with two digits (from `<<00>>' to `<<59>>'). [tm_min]
+
+o %n
+A newline character (`<<\n>>').
+
+o %O<<x>>
+In some locales, the O modifier selects alternative digit characters
+for certain modifiers <<x>>. In newlib, it is ignored, and treated as %<<x>>.
+
+o %p
+Either `<<AM>>' or `<<PM>>' as appropriate, or the corresponding strings for
+the current locale. [tm_hour]
+
+o %P
+Same as '<<%p>>', but in lowercase. This is a GNU extension. [tm_hour]
+
+o %r
+Replaced by the time in a.m. and p.m. notation. In the "C" locale this
+is equivalent to "%I:%M:%S %p". In locales which don't define a.m./p.m.
+notations, the result is an empty string. [tm_sec, tm_min, tm_hour]
+
+o %R
+The 24-hour time, to the minute. Equivalent to "%H:%M". [tm_min, tm_hour]
+
+o %s
+The time elapsed, in seconds, since the start of the Unix epoch at
+1970-01-01 00:00:00 UTC.
+
+o %S
+The second, formatted with two digits (from `<<00>>' to `<<60>>'). The
+value 60 accounts for the occasional leap second. [tm_sec]
+
+o %t
+A tab character (`<<\t>>').
+
+o %T
+The 24-hour time, to the second. Equivalent to "%H:%M:%S". [tm_sec,
+tm_min, tm_hour]
+
+o %u
+The weekday as a number, 1-based from Monday (from `<<1>>' to
+`<<7>>'). [tm_wday]
+
+o %U
+The week number, where weeks start on Sunday, week 1 contains the first
+Sunday in a year, and earlier days are in week 0. Formatted with two
+digits (from `<<00>>' to `<<53>>'). See also <<%W>>. [tm_wday, tm_yday]
+
+o %V
+The week number, where weeks start on Monday, week 1 contains January 4th,
+and earlier days are in the previous year. Formatted with two digits
+(from `<<01>>' to `<<53>>'). See also <<%G>>. [tm_year, tm_wday, tm_yday]
+
+o %w
+The weekday as a number, 0-based from Sunday (from `<<0>>' to `<<6>>').
+[tm_wday]
+
+o %W
+The week number, where weeks start on Monday, week 1 contains the first
+Monday in a year, and earlier days are in week 0. Formatted with two
+digits (from `<<00>>' to `<<53>>'). [tm_wday, tm_yday]
+
+o %x
+Replaced by the preferred date representation in the current locale.
+In the "C" locale this is equivalent to "%m/%d/%y".

+o %X
+Replaced by the preferred time representation in the current locale.
+In the "C" locale this is equivalent to "%H:%M:%S". [tm_sec, tm_min, tm_hour]
+
+o %y
+The last two digits of the year (from `<<00>>' to `<<99>>'). [tm_year]
+(Implementation interpretation: always positive, even for negative years.)
+
+o %Y
+The full year, equivalent to <<%C%y>>. It will always have at least four
+characters, but may have more. The year is accurate even when tm_year
+added to the offset of 1900 overflows an int. [tm_year]
+
+o %z
+The offset from UTC. The format consists of a sign (negative is west of
+Greewich), two characters for hour, then two characters for minutes
+(-hhmm or +hhmm). If tm_isdst is negative, the offset is unknown and no
+output is generated; if it is zero, the offset is the standard offset for
+the current time zone; and if it is positive, the offset is the daylight
+savings offset for the current timezone. The offset is determined from
+the TZ environment variable, as if by calling tzset(). [tm_isdst]
+
+o %Z
+The time zone name. If tm_isdst is negative, no output is generated.
+Otherwise, the time zone name is based on the TZ environment variable,
+as if by calling tzset(). [tm_isdst]
+
+o %%
+A single character, `<<%>>'.
+o-
+
+RETURNS
+When the formatted time takes up no more than <[maxsize]> characters,
+the result is the length of the formatted string. Otherwise, if the
+formatting operation was abandoned due to lack of room, the result is
+<<0>>, and the string starting at <[s]> corresponds to just those
+parts of <<*<[format]>>> that could be completely filled in within the
+<[maxsize]> limit.
+
+PORTABILITY
+ANSI C requires <<strftime>>, but does not specify the contents of
+<<*<[s]>>> when the formatted string would require more than
+<[maxsize]> characters. Unrecognized specifiers and fields of
+<<timp>> that are out of range cause undefined results. Since some
+formats expand to 0 bytes, it is wise to set <<*<[s]>>> to a nonzero
+value beforehand to distinguish between failure and an empty string.
+This implementation does not support <<s>> being NULL, nor overlapping
+<<s>> and <<format>>.
+
+<<strftime>> requires no supporting OS subroutines.
+
+BUGS
+<<strftime>> ignores the LC_TIME category of the current locale, hard-coding
+the "C" locale settings.

Third time lucky - pasting inline into email and resending to all previous lists.
Please note that conversion into too-small buffer size in regression test may not have expected result!
Tried to build with below and variants:
gcc -D_REGRESSION_TEST -D_COMPILING_NEWLIB -Dsniprintf=snprintf -I/usr/src/cygwin-2.2.1-1.src/newlib-cygwin/winsup/cygwin/include -o strftime-s-test strftime.c
gives undef refs for __cygwin_gettzname, __cygwin_gettzoffset, __get_current_time_locale, __tz_lock, __tz_unlock,
_tzset_unlocked
Build stc with std cmdline and current strftime works and does demo issue.

Tried to download and build from source tarball, then cygport, then
local source file, but some unobvious build prereqs missing in all
cases, as reported by ld. Finally just diffed local source against
distro and posted from gmane, with attempted fixups in the post.

Sorry, not using git yet, as I am set up with hg on BitBucket
- AIUI the output is close enough the attached should work okay.

+ size_t strftime(<[s]>, <[maxsize]>, <[format]>, <[timp]>)

+
+DESCRIPTION
+<<strftime>> converts a <<struct tm>> representation of the time (at
+<[timp]>) into a null-terminated string, starting at <[s]> and occupying
+no more than <[maxsize]> characters.
+
+You control the format of the output using the string at <[format]>.
+<<*<[format]>>> can contain two kinds of specifications: text to be
+copied literally into the formatted string, and time conversion
+specifications. Time conversion specifications are two- and
+three-character sequences beginning with `<<%>>' (use `<<%%>>' to
+include a percent sign in the output). Each defined conversion
+specification selects only the specified field(s) of calendar time
+data from <<*<[timp]>>>, and converts it to a string in one of the
+following ways:
+
+o+
+o %a
+The abbreviated weekday name according to the current locale. [tm_wday]
+
+o %A
+The full weekday name according to the current locale.
+In the default "C" locale, one of `<<Sunday>>', `<<Monday>>', `<<Tuesday>>',
+`<<Wednesday>>', `<<Thursday>>', `<<Friday>>', `<<Saturday>>'. [tm_wday]
+
+o %b
+The abbreviated month name according to the current locale. [tm_mon]
+
+o %B
+The full month name according to the current locale.
+In the default "C" locale, one of `<<January>>', `<<February>>',
+`<<March>>', `<<April>>', `<<May>>', `<<June>>', `<<July>>',
+`<<August>>', `<<September>>', `<<October>>', `<<November>>',
+`<<December>>'. [tm_mon]
+
+o %c
+The preferred date and time representation for the current locale.
+[tm_sec, tm_min, tm_hour, tm_mday, tm_mon, tm_year, tm_wday]
+
+o %C
+The century, that is, the year divided by 100 then truncated. For
+4-digit years, the result is zero-padded and exactly two characters;
+but for other years, there may a negative sign or more digits. In
+this way, `<<%C%y>>' is equivalent to `<<%Y>>'. [tm_year]
+
+o %d
+The day of the month, formatted with two digits (from `<<01>>' to
+`<<31>>'). [tm_mday]
+
+o %D
+A string representing the date, in the form `<<"%m/%d/%y">>'.
+[tm_mday, tm_mon, tm_year]
+
+o %e
+The day of the month, formatted with leading space if single digit
+(from `<<1>>' to `<<31>>'). [tm_mday]
+
+o %E<<x>>
+In some locales, the E modifier selects alternative representations of
+certain modifiers <<x>>. In newlib, it is ignored, and treated as %<<x>>.
+
+o %F
+A string representing the ISO 8601:2000 date format, in the form
+`<<"%Y-%m-%d">>'. [tm_mday, tm_mon, tm_year]
+
+o %g
+The last two digits of the week-based year, see specifier %G (from
+`<<00>>' to `<<99>>'). [tm_year, tm_wday, tm_yday]
+
+o %G
+The week-based year. In the ISO 8601:2000 calendar, week 1 of the year
+includes January 4th, and begin on Mondays. Therefore, if January 1st,
+2nd, or 3rd falls on a Sunday, that day and earlier belong to the last
+week of the previous year; and if December 29th, 30th, or 31st falls
+on Monday, that day and later belong to week 1 of the next year. For
+consistency with %Y, it always has at least four characters.
+Example: "%G" for Saturday 2nd January 1999 gives "1998", and for
+Tuesday 30th December 1997 gives "1998". [tm_year, tm_wday, tm_yday]
+
+o %h
+Synonym for "%b". [tm_mon]
+
+o %H
+The hour (on a 24-hour clock), formatted with two digits (from
+`<<00>>' to `<<23>>'). [tm_hour]
+
+o %I
+The hour (on a 12-hour clock), formatted with two digits (from
+`<<01>>' to `<<12>>'). [tm_hour]
+
+o %j
+The count of days in the year, formatted with three digits
+(from `<<001>>' to `<<366>>'). [tm_yday]
+
+o %k
+The hour (on a 24-hour clock), formatted with leading space if single
+digit (from `<<0>>' to `<<23>>'). Non-POSIX extension (c.p. %I). [tm_hour]
+
+o %l
+The hour (on a 12-hour clock), formatted with leading space if single
+digit (from `<<1>>' to `<<12>>'). Non-POSIX extension (c.p. %H). [tm_hour]
+
+o %m
+The month number, formatted with two digits (from `<<01>>' to `<<12>>').
+[tm_mon]
+
+o %M
+The minute, formatted with two digits (from `<<00>>' to `<<59>>'). [tm_min]
+
+o %n
+A newline character (`<<\n>>').
+
+o %O<<x>>
+In some locales, the O modifier selects alternative digit characters
+for certain modifiers <<x>>. In newlib, it is ignored, and treated as %<<x>>.
+
+o %p
+Either `<<AM>>' or `<<PM>>' as appropriate, or the corresponding strings for
+the current locale. [tm_hour]
+
+o %P
+Same as '<<%p>>', but in lowercase. This is a GNU extension. [tm_hour]
+
+o %r
+Replaced by the time in a.m. and p.m. notation. In the "C" locale this
+is equivalent to "%I:%M:%S %p". In locales which don't define a.m./p.m.
+notations, the result is an empty string. [tm_sec, tm_min, tm_hour]
+
+o %R
+The 24-hour time, to the minute. Equivalent to "%H:%M". [tm_min, tm_hour]
+
+o %s
+The time elapsed, in seconds, since the start of the Unix epoch at
+1970-01-01 00:00:00 UTC.
+
+o %S
+The second, formatted with two digits (from `<<00>>' to `<<60>>'). The
+value 60 accounts for the occasional leap second. [tm_sec]
+
+o %t
+A tab character (`<<\t>>').
+
+o %T
+The 24-hour time, to the second. Equivalent to "%H:%M:%S". [tm_sec,
+tm_min, tm_hour]
+
+o %u
+The weekday as a number, 1-based from Monday (from `<<1>>' to
+`<<7>>'). [tm_wday]
+
+o %U
+The week number, where weeks start on Sunday, week 1 contains the first
+Sunday in a year, and earlier days are in week 0. Formatted with two
+digits (from `<<00>>' to `<<53>>'). See also <<%W>>. [tm_wday, tm_yday]
+
+o %V
+The week number, where weeks start on Monday, week 1 contains January 4th,
+and earlier days are in the previous year. Formatted with two digits
+(from `<<01>>' to `<<53>>'). See also <<%G>>. [tm_year, tm_wday, tm_yday]
+
+o %w
+The weekday as a number, 0-based from Sunday (from `<<0>>' to `<<6>>').
+[tm_wday]
+
+o %W
+The week number, where weeks start on Monday, week 1 contains the first
+Monday in a year, and earlier days are in week 0. Formatted with two
+digits (from `<<00>>' to `<<53>>'). [tm_wday, tm_yday]
+
+o %x
+Replaced by the preferred date representation in the current locale.
+In the "C" locale this is equivalent to "%m/%d/%y".
+[tm_mon, tm_mday, tm_year]
+
+o %X
+Replaced by the preferred time representation in the current locale.
+In the "C" locale this is equivalent to "%H:%M:%S". [tm_sec, tm_min, tm_hour]
+
+o %y
+The last two digits of the year (from `<<00>>' to `<<99>>'). [tm_year]
+(Implementation interpretation: always positive, even for negative years.)
+
+o %Y
+The full year, equivalent to <<%C%y>>. It will always have at least four
+characters, but may have more. The year is accurate even when tm_year
+added to the offset of 1900 overflows an int. [tm_year]
+
+o %z
+The offset from UTC. The format consists of a sign (negative is west of
+Greewich), two characters for hour, then two characters for minutes
+(-hhmm or +hhmm). If tm_isdst is negative, the offset is unknown and no
+output is generated; if it is zero, the offset is the standard offset for
+the current time zone; and if it is positive, the offset is the daylight
+savings offset for the current timezone. The offset is determined from
+the TZ environment variable, as if by calling tzset(). [tm_isdst]
+
+o %Z
+The time zone name. If tm_isdst is negative, no output is generated.
+Otherwise, the time zone name is based on the TZ environment variable,
+as if by calling tzset(). [tm_isdst]
+
+o %%
+A single character, `<<%>>'.
+o-
+
+RETURNS
+When the formatted time takes up no more than <[maxsize]> characters,
+the result is the length of the formatted string. Otherwise, if the
+formatting operation was abandoned due to lack of room, the result is
+<<0>>, and the string starting at <[s]> corresponds to just those
+parts of <<*<[format]>>> that could be completely filled in within the
+<[maxsize]> limit.
+
+PORTABILITY
+ANSI C requires <<strftime>>, but does not specify the contents of
+<<*<[s]>>> when the formatted string would require more than
+<[maxsize]> characters. Unrecognized specifiers and fields of
+<<timp>> that are out of range cause undefined results. Since some
+formats expand to 0 bytes, it is wise to set <<*<[s]>>> to a nonzero
+value beforehand to distinguish between failure and an empty string.
+This implementation does not support <<s>> being NULL, nor overlapping
+<<s>> and <<format>>.
+
+<<strftime>> requires no supporting OS subroutines.
+
+BUGS
+<<strftime>> ignores the LC_TIME category of the current locale, hard-coding
+the "C" locale settings.

Cool, thanks for the patch. Unfortunately it doesn't apply cleanly.
There are several unexpected line wraps and there's this:
> --- a/newlib/time/strftime.c 2015-08-20 03:39:24.000000000 -0600

How did this happen? If you checkout the newlib-cygwin git repo,
strftime.c is under newlib/libc/time, not under newlib/time :o
Would you mind to attach a patch generated with git format-patch?
Thanks in advance,
Corinna

Wrong! Misread the code, strftime %s is not supported!
STC and suggested patch appended (posting from gmane), compiles, but can't
build STC as ld fails with undef refs, and I don't know all the correct
LD..., -L and -l incantations. Email me for original files.

bash printf depends on underlying strftime in newlib, which does not support
%s, as it is conditional on _WANT_C99_TIME_FORMATS being defined, and that
is presumably not defined in the config, as %s is not shown in man strftime.
Workaround for now is use
date +%s
for current time, and
date -d $(printf '%(%T)T' -2) +%s
for shell invocation time.
