test(ngMock): workaround issue with negative timestamps

Browse Source 
In some specific timezones and operating systems, it seems that
getTimezoneOffset() can return an incorrect value for negative timestamps, as
described in #5017. While this isn't something easily fixed in the mock code,
the tests can avoid that particular timeframe by using a positive timestamp.

Closes #5017
Closes #6730
