detect if date/time is daylight savings time
Hi,
Given the following datetime string "2004-03-30 13:09:28" I need to detect if it is PST or PDT?
Dalight Savings time:
Starts: First Sunday in April at 2 am local time
Ends: Last Sunday in October at 2 am local time
What I need to do is append PST or PDT accordingly.
Thanks,
Alex

More generally, you would extract the year out of your test date and use that when building the dates for startDST and endDST.

Hello,
Those times you mention for DST are very specifically USA and Canada only - in fact it doesn't even really apply to all of the USA and Canada because Fort St. John, Charlie Lake, Taylor and Dawson Creek in British Columbia, Creston in the East Kootenays, and most of Saskatchewan (except Denare Beach and Creighton) don't use daylight savings time at all.
Just to confuse things, the UK switches at one o'clock in the morning the last Sunday in March and two o'clock in the morning in October. New Zealand did their switchover three weeks ago and Australia did their's the week after that. Besides which, any region in the southern hemisphere that does daylight savings time does it at the opposite time of the year (Autumn here in New Zealand is in March/April)
