The controlling factor for when DST goes into and out of effect is located
in the file /etc/tz (SCO Xenix), Unix and others might be different??.

Mine is set up as:

	TZ=PST08:00:00PDT07:00:00;M4.1.0/02:00:00,M10.5.0/02:00:00

Which breaks down to:

	Difference in time from GMT when PST	PST08:00:00
	Difference in time from GMT when PDT	PDT07:00:00
	Month the change to PDT and when	M4.1.0/02:00:00
		(April First Week Sunday)
	Month the change to PST and when	M10.5.0/02:00:00
		(Oct Fifth Week Sunday)

I found this information in the man pages tz(M).

If congress changes the start and or end, all you need to do is change
this string to match what the change is.  If it is moving to end of
April then:

	TZ=PST08:00:00PDT07:00:00;M4.5.0/02:00:00,M10.5.0/02:00:00
