Um, I have a single boot system (Source Mage only), the time is set for local 
not UTC, and it automatically reset the time for me.  I am running KDE, so 
that may have been what did the time adjustment.

I don't think the time zone has anything to do with it, unless it's set for 
some place like Arizona, which doesn't do day light savings time.

Also, my /etc/localtime is not a link, but it appears to be a copy of the 
specific time zone file.
