GAE pytz
A fork of pytz which works on Google App Engine.
Based on http://appengine-cookbook.appspot.com/recipe/caching-pytz-helper/ but modified so that it can be imported normally with import pytz.
Install from PyPI:
$ pip install gae-pytz
The project home is on GitHub: https://github.com/potatolondon/gae-pytz/
How to update the zone info database
Clone the gae-pytz repository and download the source distribution of pytz:
$ git clone https://github.com/potatolondon/gae-pytz.git
$ cd gae-pytz
$ pip install --download . --no-binary :all: pytz
That should download the source tarball for pytz and save it in the current directory. Extract the zone info database and create a new zip (you need to change the name for the pytz source tarball):
$ python makezoneinfo.py < pytz-2016.6.1.tar.gz > pytz/zoneinfo.zip
