This is a discussion on Is there a perl package, or data in a form easily used by a perlscript, that can be used to determine when to change to or from daylightsavings time? - Perl ; On Nov 9, 5:27 am, "Dr.Ruud" <rvtol+n...@isolution.nl> wrote: > Ted Byers schreef: > > > Dr.Ruud: > >> Peter Wyzl: > >>> but is there some 'authorative source' of what all the different > >>> timezones are and the daylight times ...

All I'm after is to make sure the timezone data I have is up to date.
I routinely use ActiveState's PPM to install packages, and I use CPAN
as a fallback option when the package I'm after isn't in a PPM
repository. The documentation for DateTime::TimeZone doesn't say
which version of the Olson data it uses, so I can't be sure it uses
the current Olson data unless someone can confirm that.
