This patch also does away with an incompatibility between Jython
and CPython.

test_formatdate_zoneoffsets() => test_formatdate_localtime(): Do the
sign corrected calculation of the zone offset.

negative modulus won't return the right values.  So always do positive
modulus on an absolute value and twiddle the sign as appropriate after
the fact.

use the correct way to test for epoch, by looking at the year
component of gmtime(0).  Add clause for Unix epoch and Mac epoch (Tim,
what is Windows epoch?).

Also, get rid of the strptime() test, it was way too problematic given
that strptime() is missing on many platforms and issues with locales.
Instead, simply test that formatdate() gets the numeric timezone
calculation correct for the altzone and timezone.

incorrect for "uneven" timezones.  This algorithm should work for even
timezones (e.g. America/New_York) and uneven timezones (e.g.
Australia/Adelaide and America/St_Johns).
