Reminder to everyone: the current state of the art for getting up to date tz info for Python is "pip install pytz".

If any proposal is more complicated than that, there's absolutely no point in changing anything. The version I liked best so far is for Python to just install a copy of pytz automatically (shipping it in the installer rather than downloading it). OS packagers would then take it out (replacing it with a dependency on a pytz emulator that used the system database instead).

Lennart's original proposal was to land the machinery from the current pytz package into the stdlib, leaving the data part as a separately-installable package. Lennart also proposed some kind of (maybe configurable) policy for looking up the Olson-based timezonedb.

I'm fine with Lennart's proposal, but want to argue against including any copy of the Olson db in Python itself: I don't believe the set of folks who need it but can't do the equivalent of 'pip / easy_install ' is big enough to outweigh the downside of bundling immediately-stale data, and hoping that everybody else remembers to configure it out.
