What should 'tomorrow' be?
As you might know, I'm reimplementing PHP's date/time routines. At the moment PHP doesn't handle this well I think. But what should PHP's strtotime() do with "tomorrow". Always 24 hours which will make "2005-10-29 02:00am tomorrow" show "2005-10-30 01:00am" because time changes back to non-DST that day... but when it should always exactly a day "2005-04-02 02:30am tomorrow" does not exist although "2005-10-29 02:00am tomorrow" will then correctly show "2005-10-30 02:00am"... what is your opinion on this?

I guess I'm predudiced since I live in a country that doesnt have DST ;)
But the templation would be to ignore DST, in everything, except: $date->toStringLocale('%Y %d %h'); $date->parseWithLocale('12/....');
But I suspect it's not a simple as that...
Personally, I assume that when you ask for 'tomorrow,' what you'll get back is a date, not date-time. But maybe I'm the only one.
I think that it should return tomorrows date at midnight rather than saying date + 24 hours. If I remember correctly to my perl days Date::Manip worked that way which was quite useful.
I agree with Jacques - if yo always get a date at midnight, the results are much more predictable (an thus easier to work with). It also goes in the direction that Ryan mentioned about only getting back a date.
Hi Derick!
I guess this case is pretty rare (it's just 2 hours per year, that get lost), therefore, I'd suggest to move to 3:00 when the time between 2 and 3 does not exist.
Another possibility would be to make it configurable how to deal with the DST switch times (eg. "move to next hour", "move to last hour", "error",...).
