Here are proposed changes to the "southamerica" file to reflect the decision
to remain on DST throughout 2011 on a trial basis.

If no problems are found, I'll update the ftp site on 2011-04-11 (before
2011-04-17, which is when the change first matters).

  # For now, we'll just record the time in Stanley, since we have no
  # better info.
  
+ # From Steffen Thorsen (2011-04-01):
+ # The Falkland Islands will not turn back clocks this winter, but stay on
+ # daylight saving time.

+ # </a>
+ #
+ # We have gotten this confirmed by a clerk of the legislative assembly:
+ # Normally the clocks revert to Local Mean Time (UTC/GMT -4 hours) on the
+ # third Sunday of April at 0200hrs and advance to Summer Time (UTC/GMT -3
+ # hours) on the first Sunday of September at 0200hrs.
+ #
+ # IMPORTANT NOTE: During 2011, on a trial basis, the Falkland Islands
+ # will not revert to local mean time, but clocks will remain on Summer
+ # time (UTC/GMT - 3 hours) throughout the whole of 2011.  Any long term
+ # change to local time following the trial period will be notified.
