  # From Paul Eggert (2015-03-03):
  # For now, assume that the extension will persist indefinitely.
  
+ # From Juan Correa (2016-03-18):
+ # The decree regarding DST has been published in today's Official Gazette:
+ # http://www.diariooficial.interior.gob.cl/versiones-anteriores/do/20160318/
+ # http://www.leychile.cl/Navegar?idNorma=1088502
+ # It does consider the second Saturday of May and August as the dates
+ # for the transition; and it lists DST dates until 2019, but I think
+ # this scheme will stick.
+ #
+ # From Paul Eggert (2016-03-18):
+ # For now, assume the pattern holds for the indefinite future.
+ # The decree says transitions occur at 24:00; in practice this appears
+ # to mean 24:00 mainland time, not 24:00 local time, so that Easter
+ # Island is always two hours behind the mainland.
