 "hwclock --systz" sets the wrong time when hw clock tracks localtime

Have to use gnome Date and Time app to manually set clock to correct local time. BIOS time is set to local time.  Time is correct on this machine when booting Fedoras 13, 14, and 15.

Setting severity to high since wrong time impacts yum updates and also causes filesystem checks to see future dates.
Comment 1 Lennart Poettering 2011-07-18 20:29:02 UTC 
Can you please boot with "systemd.log_level=debug" and "systemd.log_target=kmsg"? and paste the output of "dmesg" after boot here?
Comment 2 Clyde E. Kunkel 2011-07-18 21:22:28 UTC

dmesg output requested

As requested.
Comment 3 Clyde E. Kunkel 2011-07-26 17:18:45 UTC 
Clock now being set 4 hours ahead vice 8.  Don't know what led to this change.
Comment 4 Lennart Poettering 2011-08-29 12:28:41 UTC 
Hmm, so this is weird. systemd should log a message like "RTC configured in localtime, applying delta of %i minutes to system time" when it applies the local RTC offset. This message does not appear in your output. Can you retry this with the current version of systemd from f16, and see if you can reproduce this issue? Do you see this log message then?
Comment 5 Clyde E. Kunkel 2011-08-29 13:37:33 UTC 
Sorry, had to reinstall and the issue is resolved with a reinstall.  So, probably I exacerbated the original problem with some poor hacking on my part when the problem first appeared.

Thank you for looking at this. Closing now--Insufficient Data, I guess.
