Not able to run isodatetime tests under different time zone

[kinow]

Hi,

I was trying to build and run the tests of isodatetime, but running the tests as in Travis CI (or even with python -m unittest -v isodatetime.tests) result in:

Test the recurring date/time series parsing. ... ok

======================================================================
FAIL: test_timepoint_strftime_strptime (__main__.TestSuite)
Test the strftime/strptime for date/time expressions.

Ran 17 tests in 103.576s

FAILED (failures=1)

(error in %s, one time got 1014985802, and the other 1014939002)

Debugging the test, I think it was in the Duration#get_days_and_seconds that I realized it was getting the time for one day before. It means that the time that was 1st of March 2002 was being treated as NZ time, and then when retrieving the seconds, it would first convert the time to UTC, resulting in Feb 28th, time around 11:30 AM.

Tried some monkey patching, or re-defining the timezone in the command line with no luck. Even though users could be asked to set the TZ to UTC when running tests, I think it would be harder/frustrating to some users. Also, writing code for isodatetime forces me to fiddle with my TZ in order to run all the tests.

Found a way to run the tests (thanks to co-worker Wolfgang). Just had to use

TZ=UTC python -m isodatetime.tests
