Sorry, this doesn't fix it either!!!!!  
Low pilot light on here:
It seems that UNIX programmers that live on the east coast think that time
revolves around them.
pilot light off :-)

Seriously, the UNIX kernel seems to assume EST/EDT unless explictly set to
some other time zone.  We in the other zones are always having to be
careful that the TZ environment is set properly.  Particularly for
programs that are to be run by cron.  If not, we are "mailed" messages or
have files created that are all dated with EST/EDT times.

With regard to this problem, the way I fixed it was to move the line:
	TZ=`cat /etc/TZ`: export TZ
to a postion before the "date -" command is run.  This lets the system
know it is to use the proper offset when extracting the date from the
hardware clock.
Please advise use if this would create any other problems.
