             Bug #: 15071
           Summary: Daylight Savings and Standard time reversed.
           Product: glibc
           Version: 2.13
            Status: NEW
          Severity: minor
          Priority: P2
         Component: localedata
        AssignedTo: unassigned@sourceware.org
        ReportedBy: jaquig@shaw.ca
                CC: libc-locales@sourceware.org
    Classification: Unclassified


Noticed recently that for some reason GNU/Linux seems to think that winter in
the Northern Hemisphere is Daylight Savings time.
[ a friend in NZ gets the same backwards daylight / standard time display on
his system ]

Checked several distributions, all showing same issue, and various versions of
glibc, oldest being 2.13.
haven't yet found the specific code that is causing the reversal.

Daylight Savings or Standard time is not going to severely impact the system,
it is a user interface display bit only, so not a very important issue.
and with it having been in for 4 releases and not reported obviously not
something most worry about.

$ TZ=America/Los_Angeles date

This seems correct?

Can you go into more detail exactly what commands give exactly what output and
what output do you expect, ideally based on the `date` command? Are you sure
your date is set correctly?

[00:14:10 PDT] Krash: sorry jaq got family here, and they're driving me fucking
INSANE
[14:35:50 PDT] Shippy69: Mc here?

today in Skype is easiest to show what is wrong.
the above shows 2 posts from today, one at 00:14:10 and one at 14:35:50
both specify PDT, yet it should be PST [ STANDARD time ]
so the locale is switching that.

I see. I'm not sure if Skype is not using some custom functions, though, are
you sure this is not Skype-specific? It would really be best if you could also
post output of:

cat /etc/timezone
date

hmm, oddly no /etc/timezone file.
but date is giving standard time. so you are right, it is skype specific.
[ which I had already contacted their support ]
