++# The Chilean Government has decided to postpone the entrance into winter time
++# (to leave DST) from March 11 2012 to April 28th 2012. The decision has not
++# been yet formalized but it will within the next days.
++# Quote from the website communication:
++#
++# 6. For the year 2012, the dates of entry into winter time will be as follows:
++# a. Saturday April 28, 2012, clocks should go back 60 minutes; that is, at
++# 23:59:59, instead of passing to 0:00, the time should be adjusted to be 23:00
++# of the same day.
++# b. Saturday, September 1, 2012, clocks should go forward 60 minutes; that is,
++# at 23:59:59, instead of passing to 0:00, the time should be adjusted to be
++# 01:00 on September 2.
