test_formatdate(): Integrating Jack's 22b2 branch fix for Mac epoch:

    More changes to the formatdate epoch test: the Mac epoch is in
    localtime, so east of GMT it falls in 1903:-( Changed the test to
    obtain the epoch in both local time and GMT, and do the right
    thing in the comparisons. As a sanity measure also check that
    day/month is Jan 1.
