Bug description:
  [Impact]
  All users affected by this time zone.

  [Test Case]
  See https://wiki.ubuntu.com/StableReleaseUpdates?action=show#tzdata

  [Regression potentional]
  Minimal, no code change and addresses the latest upstream time differences.

  I am installing Ubuntu 12.04 LTS and despite choosing Port-au-Prince
  from the global map in Ubiquity, the time zone / resulting time is
  wrong. It will show for example 8AM when in fact it is 9AM. I've
  compared this with local time (radio, local mobile phones) and with
  different Internet sources to confirm.

  TimeAndDate.com reports the following correct information:

  Standard time zone:	UTC/GMT -5 hours
  Daylight saving time:	+1 hour
  Current time zone offset:	UTC/GMT -4 hours
  Time zone abbreviation:	EDT - Eastern Daylight Time
  Daylight Saving Time	DST started on dimanche 11 mars 2012, 02 h 00 local standard time
  DST ends on dimanche 4 novembre 2012, 02 h 00 local daylight time

  It's even more interesting that this change only happens *this year*:
  http://www.timeanddate.com/worldclock/timezone.html?n=709

  I believe any Ubuntu system (and probably other Debian derivatives)
  running in this timezone are 1 hoour late as a result.

  UPATE: This was fixed in tzdata 20120c1 and above, however such version won't be updated in Ubuntu for some time (low priority according to Canonical). To check your version:  dpkg -l tzdata

  A workaround is provided in the comments below.
