Set Time Zone

I am new in dreamhost and this is my first post.
I have a little problem, my account logs uses server timezone (GMT-7, if I am not mistaken). I live in Spain and my timezone is GMT+1 (now is GMT+2 due to DST). The problem is evident and my awstats report are a little crazy! hehe

How can I, set my account time zone to GMT+2? It is possible?
Thanks for your time!
