Okay, well then you can either lie about whether you're in a daylight
saving time zone:
% perl -MDate::Parse -le 'print str2time("Sun Oct 31 01:00:00 PST 2004") \
- str2time("Sat Oct 30 23:00:00 PST 2004")'
7200
vs. what you don't want:
% perl -MDate::Parse -le 'print str2time("Sun Oct 31 01:00:00 PST 2004") \
- str2time("Sat Oct 30 23:00:00 PDT 2004")'
10800
Or you can just make the timezone the never-changing GMT:
% perl -MDate::Parse -le 'print str2time("Sun Oct 31 01:00:00 GMT 2004") \
- str2time("Sat Oct 30 23:00:00 GMT 2004")'
7200
