Subject: Re: Cygwin strptime() is missing "%s" which strftime() has
Date: Mon, 24 Jul 2017 09:21:00 -0000	[thread overview]

> But that's just scanning a decimal integer to time_t.

It's not a question of whether I can or can't convert a string into an integer, rather it's a question about portability of code that uses %s for both functions and expects it to work unchanged in the Cygwin environment.  Also, strptime() was designed to be a reversal to strftime() (from the man-pages: the  strptime() function is the converse function to strftime(3)) so both are supposed to "understand" the same basic set of formats.  Because of Cygwin's strptime() missing "%s", the following also does not work even from command line:

$ date +"%s" | strptime "%s"
strptime: cannot make sense of `1500861577' using the given input formats

Thank you,
