Here's my first shot at a script. It combines Zefram's suggestion to
use $dt-epoch() and Eugene's recommendation to measure the intervals
at noon instead of at midnight. Next, I'd like to refactor it
using...um...I'm not sure, but something other than $dt-epoch().

Interesting, Australia/Lord_Howe does a half-hour DST shift every year.
How do I compute the number of hours in a day in a specific time zone?
Let's say I want to iterate the days of the year from Jan 1 thru Dec 31
and print the number of hours in each day in the America/New_York time
zone. I expect 363 days to have 24 hours, one day to have 23 hours, and
one day to

Try this:
use DateTime;
for(my $today = DateTime-new(year=2007, time_zone=$ARGV[0]); $today-year ==
2007; ) {
(my $tomorrow = $today-clone)-add(days=1);
print $today, ,

It ought to be possible to do the interval calculation using
DateTime::Duration instead of -epoch, but the behaviour of DT::D is
unreasonably confusing and I couldn't get it to work. (Strangely, I got
a version that worked fine for America/New_York, where all the days are

DateTime cannot handle fractional leap hours.
See the source code of subtract_datetime(), section This is a gross
hack, where the length of the leap hour is hardcoded in the lines

This should probably
