Currently at the header, the time is:
Thu, 22 Oct 2009 02:43:36 +0200GMT

My server time is:
Qua Out 21 22:43:36 BRST 2009

Current timezone set on Debian:
America/Sao_Paulo.

When I buy something, the order date and time is set to the same as my server.
but, why Zen Cart is showing the wrong hour?
