I really don't understand this one, I have solved this kind of problem multiple times in different languages on different platforms.

Really? Did you account for all possible issues: - are T1 and T2 in the same time zone? - did Daylight Saving Time occur between T1 and T2? - did rules for DST changed between T1 and T2? - where any leap second jumps between T1 and T2? Randall knows best :D

Oh dear, seems I have never needed that much accuracy after all. And in some cases such deliberations would not be possible on target platform.

And how many commercial breaks were there during that period?

Always interchange and compare dates/times in UTC. I wouldn't bother with leap seconds unless you need to know the seconds, and you generally don't.

I agree with you, but I know some people in the lounge were arguing for using local time. Go figure!

Say it ain't so. Probably the sort who wear digital watches and read off the exact time to the second. :rolleyes:

At some point it is not possible to generalize this sort thing. I worked on a system where a work flow needed to be resolved within '3 business days'. So a casual developer is going to look at that and perhaps understand it means 'skip the weekends' But in fact it is quite a bit more complex. - A business day consisted of 8 hours. - Holidays were not business days. (This of course required adding a complete sub-system to allow them to specify holidays.) - A work flow could be started in California but would be viewed and acted upon in New York. So obviously time zones were relevant. Also consider the complications for the following sort of report - Company operates brick and mortar stores across the country - Company has an online site to order products - VP asks for a report that summarizes sales during the 'lunch hour'
