Timedate()



I am using Windows XP Professional and the system time according to Windows is correct but when I run the timedate() function reports the wrong time and day.  Running it now as I send this e-mail it reports that the day is Sat and the
date and time are 02:21:52 Sat, 7/12/2008 (GMT+1)

The correct time is 9:22:52 Fri 7/11/2008.

Am I doing something wrong?

I just issued 

timedate();

using Maxima 5.15.0.

I think this is a time zone issue but I don't know the function to change the timezone to EST which is right for Philadelphia, PA.
