Time Offset by 6 hours?

[Arie]

OK, I think I can solve most problems, but this one has be baffled :erm:

All was working fine. I *did* restart MySQL last night, after tweaking 1(!) setting:

I increased sort_buffer_size=512KB to sort_buffer_size=1M

This morning I noticed that these times are off by 6 hours:

You last visited xxx
Post time (shown on new posts & replies)

The forum time shown at the bottom are correct (in my case All times are GMT +1. The time now is xxx).

Checked server time

date
Sat Mar 10 07:54:42 CST 2012

That's correct.

Check MySQL time

mysql> select now();
+---------------------+
| now() |
+---------------------+
| 2012-03-10 07:55:31 |
+---------------------+
1 row in set (0.00 sec)

Both Apache & php.ini are set to the correct time zone

php.ini

date.timezone = 'America/Chicago'

httpd.conf

SetEnv TZ US/Central

What am I missing? I've been running my forum for about 2 weeks on this new server (and years on the old one). I had been tweaking MySQL for the last while and restarted previously, no problems until this morning...
