I've run the test hundreds of times and observed no failures on
my WindowsME box.

The traceback above shows the pattern matches through the timezone
and fails on 'EDT' vs 'EST' with the EDT being correct for this time of year.

The EDT version comes from time.strftime().
I suspect the pattern's timezone is extracted from
another source and the difference only shows up
on certain platforms.  This doesn't explain the
transient nature of the bug or what needs to be
changed, but I hope it helps a bit.
