The latest patch to the tz data, tzdata2005h, shows that Haiti stopped observing DST since 1997. A correspondent, Risto O. Nykänen, wrote me that Haiti is now on DST. I searched for confirmation, and I found a press release on the Web page of the Haitian Consulate in Chicago, http://www.haitianconsulate.org/press.html, dated 03-31-05. Translated from French, it says: "The Prime Minister's Communication Office notifies the public in general and the press in particular that, following a decision of the Interior Ministry and the Territorial Collectivities [I suppose that means the provinces], Haiti will move to Eastern Daylight Time in the night from next Saturday the 2nd to Sunday the 3rd. "Consequently, the Prime Minister's Communication Office wishes to inform the population that the country's clocks will be set forward one hour starting at midnight. This provision will hold until the last Saturday in October 2005. "Port-au-Prince, March 31, 2005" Gwillim Law
