My mistake, as you can see there is no tzdata supplied with package, as it is in pypi source archive (https://pypi.python.org/pypi/pytz/)
$ dpkg -L python3-tz /. /usr /usr/lib /usr/lib/python3 /usr/lib/python3/dist-packages /usr/lib/python3/dist-packages/pytz /usr/lib/python3/dist-packages/pytz/__init__.py /usr/lib/python3/dist-packages/pytz/exceptions.py /usr/lib/python3/dist-packages/pytz/reference.py /usr/lib/python3/dist-packages/pytz/tzinfo.py /usr/lib/python3/dist-packages/pytz/tzfile.py /usr/lib/python3/dist-packages/pytz-2012c.egg-info /usr/lib/python3/dist-packages/pytz-2012c.egg-info/dependency_links.txt /usr/lib/python3/dist-packages/pytz-2012c.egg-info/PKG-INFO /usr/lib/python3/dist-packages/pytz-2012c.egg-info/zip-safe /usr/lib/python3/dist-packages/pytz-2012c.egg-info/top_level.txt /usr/share /usr/share/doc /usr/share/doc/python3-tz /usr/share/doc/python3-tz/changelog.Debian.gz /usr/share/doc/python3-tz/copyright I hitted error with my local django installation, but error was not in system package, sorry for that. To find what utc offset for 'Europe/Moscow' run: $ python3 -c "import pytz, datetime; print(datetime.datetime.now(pytz.timezone('Europe/Moscow')).strftime('%z'))" My output is: +0300 It is correct.
