The error is from datetime and it is from python
distribution. The tz uses operating systems information
about the timezones and as the zdump shows, it gets there
utcoffset that is not full minute.

What's this?
>>> from dateutil import tz
There is no `dateutil` module in the Python distribution (in
which case problems with `dateutil` should be directed to
its developers, not to the Python tracker).
