You mean the big list of timezones and the mapping that turns a name
like 'Europe/Worksop' into some data about timezones and the dates
they apply?

It would be nice, perhaps.  But not really worth the effort when we
can just ask the user a couple of questions at configure time.  What
is your timezone?  Does it observe DST?

I don't think this data is installed in a standard place, it might be
stuck in the installer somewhere.  If it is installed then it would be
nice to use it but as I said, a lot of work for not very much reward
(given the different formats this data will be in on different
platforms).
