I think this is what I was alluding to earlier. Some events are dependent on the user's local time zone, whatever that might be at the moment, and some are dependent on a fixed geographical time zone.
On a side note, when is a day not even close to 86,400 seconds?
I found a bug in my app last night where it displayed Sunday twice next week. Very odd. Until I discovered that for tcl, next Sunday where DST comes into effect is a day with 90,000 seconds. It was not suff for me to just add 86,400 to the last clock scanned val, I needed to add "1 day" to it. Presumably there's a day in April with only 82,800 seconds....
