I think we should include Saint Barthelemy in the tz database, probably in the northamerica file. Currently I don see any mention of it, so the minimum would be to include the island in an appropriate parenthesis for one of the current timezones. The island has a population of 6,852 in the 1999 consensus. The other reason it should be included is that it has its own country code BL, so it should be in the iso3166.tab file. However wikipedia http://en.wikipedia.org/wiki/Saint_Barthelemy and the CIA factbook https://www.cia.gov/library/publications/the-world-factbook/geos/tb.html claim that it uses DST, the first as usual without any detail, while the latter gives the dates starting 20. March and 17. October (for 2007 only?). I have tried to find information on the French-only homepage of the island, but my French skills are definitely not up to the task - perhaps there is no mention of DST in these pages anyhow. The page http://www.st-barths.com/guidepgs/practical.html#10 claims that there is no DST in use in Saint Barthélemy. As usual I welcome any other information that anyone might have to shed light on the possible application of DST on Saint Barthélemy.
