As expected, your change affects the following zones, for dates after
the spring of 2475 for:
Africa/Cairo
America/Godthab
Antarctica/Palmer
A quick check indicates the expected fix, following DST rules into the
future.
And I'm also getting different output for only times between
2009-12-30T20:00:00 and 2009-12-31T20:00:00 (local time) for
America/Eirunepe, which is strange.

The America/Godthab problem is a fencepost error; the proposed change
below fixes it.
