Re: DSTlaw

It is confusing when you state that the parameters begin_week and end_week designate the weeks in the months, and later you state that, in the example, 3 -1 1 describes "second sunday in March". Not alwasy the second sunday will be the sunday of the second week, as we have in Brazil, this year, the beginining of DST will be on Oct 21st midnight, so, which is the third sunday of the month, but, the sunday of the third week would be the 14th. And we can't be sure of the correct DSTLAW settings then.
