Ouch. Thanks for the heads-up. So they changed their minds again,
with only four days' notice? Their new rule is more historically
compatible; perhaps that's why.
Currently we have them changing at 2006-09-25 at 01:00 local time.

I'll CC: this to Hammad Hassan to get his feedback, but the
following patch should do the trick. This is in addition to
the Syria and Uruguay patches I sent earlier this week.
