Description Michal Jaegermann 2011-12-20 23:32:20 UTC
Description of problem:

After an update to the last rawhide glibc-2.14.90-25.fc17.x86_64 all times are displayed _only_ like that: "Tue Dec 20 23:19:47 UTC 2011".  After a reboot timestamps in log files also switched from a local time to UTC.  That despite that /etc/localtime exists (and it happens to be the same one as /usr/share/zoneinfo/America/Edmonton and it did not change for a long time).

'strace' on 'date' shows that /etc/localtime is opened for reading but a timezone information is disregarded.  Setting TZ only changes a timezone marker but other than that 'date' and 'date -u' show the same time.

Version-Release number of selected component (if applicable):
glibc-2.14.90-25.fc17.x86_64

How reproducible:
always

Additional info:
More precisely I do not have an absolute evidence that glibc is a culprit and I did not try to revert that update but it is hard to imagine what else on the list of the last batch of updates could have such pervading influence.  I have a feeling that this may be related to a "fix" for bug 767696.

I can confirm that downgrading to the latest one from the F16 testing updates fixes it.

Comment 2 Steven Usdansky 2011-12-21 12:45:18 UTC
Reverting to glibc-2.14.90-23.fc17.x86_64 fixed the problem for me.

Looks like we lost this fix with update from master:

Comment 4 Jeff Law 2011-12-21 17:15:45 UTC
It hadn't been committed to the master when I updated rawhide; I didn't realize it was going to have this impact.  I'll resync shortly to address a few random issues.

Comment 5 Michal Jaegermann 2011-12-24 01:20:05 UTC
With glibc-2.14.90-26.fc17 displayed times look as before (but parts of logs are already in the future :-).
