I support a large Perl app. The IT guys are complaining that there is
some vague problem with things being an hour off. I'm still waiting for
more details ... meanwhile are there any known Perl or CPAN issues with
the recent daylight savings time change?

If it were actually a crosspost that'd have been okay, but it was
a multipost instead. Please don't do that!

Any long-running app that reads in timezone configuration at startup, then
does not reread it in, is subject to potential problems. I would suspect
any daemons that have not restarted since the changeover. (If you
run mod_perl, for example, and the httpd's are still running, you may
see some issues.)

This would only be the case if the timezone files had been updated since
the process started (ie: someone applied a patch lately). If they were
right at the start then a switch to/from shouldn't affect things (and if it
does it *shouldn't*).

Just because I've written it doesn't mean that
either you or I have to believe it.

For anyone else who has this problem ... here's the solution.

Turns out that if your code uses DateTime, you need a new timezone file.
