Need help fixing testcases with time-difference

[Hartmut Goebel <h.goebel@crazy-compilers.com>]

Hi,

I'm currently working on django, the web application framework.
Unfortunalty some tests fail. These are all testing time- and timezone
calculations.

Failures are like this:

AssertionError: datetime.timedelta(0, 3600, 16) not less than
datetime.timedelta(0, 2)

which means the returned time difference is ca. 1 hour, but allowed are
only 2 minutes. The testcase os this one
https://github.com/django/django/blob/master/tests/file_storage/tests.py#L239>

I already added tzdata to native-inputs, but this does not solve the issue.

Any hints?
