I never had any luck finding anything to give me the future DST changes for
a timezone so I worked out how to get it on my own, but recently I upgraded
from something like DateTime 0.36 to 0.74 and something really strange is
happening.
In my code I set the date to the start of the year and then
Back in 2007 I wrote about some code I wrote in 2003. No idea if it'd be
useful.

We don't have an API for that. We've discussed it a bit, and will most
likely add such a thing to the DT:TZ API after we've switched to the
reimplemented DT:TZ, scheduled for 2012-09-01.

I wasn't aware of the bit about epoch Zefram pointed out. Can someone answer
this related hypothetical for me?

It is a linear count of mean solar seconds, but not
So is that a bug in DateTime? If I subtract one epoch time from another and
add shouldn't they end up together? Or is it just too weird to code for?
Maybe a better solution than adding seconds would be just moving to that
epoch slice, I'd have to create a new datetime using from_epoch (unless
Not a bug in DateTime. This is consistent with the C libraries that underpin
Perl and other stuff. If you call the internal time() function every second
over a leap second you'll see the same epoch value twice. It's about defining
what the epoch second actually means. It's the number of solar
