Date field shows GMT time

[Albert Hopkins]

Whenever I get messages from qmail (MAILER-DAEMON) the Date: field shows 
time in GMT (-0000).  However, we are in the North American Central time 
zone.  Our system is set with the correct time zone (well, at least date 
says CDT).  Is there any way to tell qmail to use CDT when composing bounce 
messages, etc?
