It seems to me that "truncate-to-day" logically means the start of the
day which, due to DST rules, does not necessarily mean 00:00:00. The
later is a fallacy of non-DST thinking. So if the existing DST rules
for a time zone define a day as starting @ 01:00:00, shouldn't a DST
intelligent framework such as DateTime treat truncate-to-day routines
accordingly?
The real problem is that there's no date-only class that's part of
DateTime.
When someone says "today" they probably don't want "1:00AM", they want
"2009-02-24" at any time.
I'm sure that if the behavior were changed so that it found the first
valid time, someone would come along later and complain about how this is
weird:
my $tomorrow = DateTime->today()->add( days => 1 );
Why is it 1:00 AM?
Nothing has made me hate date & times as much as working on DateTime ;)
