Update pytz timezone definitions

I am looking at using pytz in a scheduling application which will be
used internationally . I would like to be able to update the definition
files that pytz uses monthly or bi-monthly.

As far as I can tell, pytz seems to be updated (fairly) regularly to
the newest tzdata, but I don't want to have to update my pytz, just
it's definitions.

http://www.twinsun.com/tz/tz-link.htm says that pytz "compiles tz
source into Python." Does this mean that there is already a method for
updating the definitions?

Any help would be greatly appreciated, even if it is to point out
something obvious which I over looked.

pytz's build process is rather complicated (e.g., a list of all time
zones is appended to pytz/__init__.py). I really don't think it would be
worth the effort.

python-dateutil [1] [2] provides time zone support similar to pytz's,
among other features. It keeps the time zone files in a tarball and I'm
pretty sure it would be easy to update.

I still don't get why you'd want to go to the effort though. Upgrading
the whole package is easy. It's not like pytz gets a new API every version.

Does someone know if the module pytz (http://sourceforge.net/projects/pytz/) is thread-safe ? I have not seen it explicitely stated, and just wanted to be sure, as I want to use it. That's because in the file pytz/tzinfo.py, I see global variables _timedelta_cache, _datetime_cache, _ttinfo_cache, which are dictionnaries and are used as cache. I always thought that you must protect shared data with locks when multithreading, but I don't...

Hi all, I'm trying to handle two projects in one solution (.net 2002, both projects are VB). The first project contains only some public constant definitions (for the moment) and compiles into class libarary. The second one is builds an executable which has a reference to the assembly of the first project to retrieve global constant definitions. The whole thing works fine as long as no definitions are changed in the library project. ...

Hi All, Using pytz, I am facing a problem with Asia/Calcutta, described below. Asia/Calcutta is actually IST, which is GMT + 5:30. But while using pytz, it was recognized as HMT (GMT + 5:53). While I digged into the oslan database, I see the following: # Zone NAME GMTOFF RULES FORMAT Zone Asia/Calcutta 5:53:28 - LMT 1880 # Kolkata

Hi All, I am using pytz.common_timezones to populate the timezone combo box of some user registration form. But as it has so many timezones (around 400), it is a bit confusing to the users. Is there a smaller and more practical set? If not, some suggestions on how to handle the registration form effectively would help me a lot. thanks Sanjay
