Let me guess: running Tor in an OpenVZ container?

The timezone is an *offset* applied to the UTC time.  It doesn't matter 
what offset is applied if the actual (UTC) time is wrong.  Try this:

   ntpdate -q pool.ntp.org

to get a 2nd opinion on how far you are from the actual time.  It won't 
vary depending on the configured timezone.

OpenVZ containers inherit their system time from the host.  (That '-q' 
is for query because that is all you can do - you can't set the time.) 
Your only recourse is to open a ticket with the VPS vendor and tell them 
to fix the system time on the node that is hosting your VPS.
