Just correcting the URL: <

As a result of the above Decree I believe the America/Rio_Branco timezone
shall be modified from UTC-5 to UTC-4 and a new timezone shall be created to
represent the the west side of the Para State. I suggest this new timezone
be called Santarem as the most important/populated city in the affected

This new timezone would be the same as the Rio_Branco timezone up to the
2008/06/24 change which would be to UTC-3 instead of UTC-4.
