Comment 17 for bug 91637

Eugene's fix (alone) will only solve the related problems until October, or until this is fixed in stable.

For long-term fix, just in case, in the TZ file, under BEGIN:STANDARD, also change:

RRULE:FREQ=YEARLY;BYMONTH=10;BYDAY=-1SU
to
RRULE:FREQ=YEARLY;BYMONTH=11;BYDAY=1SU
