Different (and wrong) timezones reported by both strftime(3) and date(1)
Sun Nov 2 10:49:00 GMT 2014
I've run into an issue of both strftime(3) and date(1) reporting
different (and wrong) timezones. I'm in the MSK timezone (switched
from +0400 to +0300 on 10/26/14). However, as of today, 11/2/14, the
following simple program
time_t tt = time(NULL);
tm* lt = localtime(&tt);
strftime(&buf, 128, "%H:%M:%S%z\n", lt);
outputs "14:10:00+0330". Both time and timezone here are wrong (it
should be "13:10:00+0300" instead, and Moscow is never in the "+0330"
Running "date +'%H:%M:%S%z'" at the same time produces
"14:10:00+0400", which is better, since Moscow was in the "+0400"
timezone a week ago, but it still should be "13:10:00+0300" as in the
Curiously enough, `unset`ting the TZ environment variable fixes both
of these issues.
Anyway, I hope somebody will be able to fix this issue anytime.
