It would be kind of ironic if they actually did change their time zone in 2000, in which case it would not be a good example of somewhere not deserving its own entry in the database. On Fri, Feb 27, 2026 at 8:14 PM Paul Eggert <eggert@cs.ucla.edu> wrote:

Which is correct?
Good luck figuring that out!
As Crozet’s only settlement, the base Alfred Faure on Île de la Possession, is supplied by ship from Réunion[1], and the station’s longitude is a bit west of Réunion’s, it seems unlikely that its time zone would be an hour east of Réunion’s.
Still, it would be nice to have more definite confirmation. The best source that I could find that might help resolve the confusion was a 2015 Le Monde article[2] quoting a letter from François Garde, the superior administrator of French Southern and Antarctic Lands from 2000 through 2004, suggesting that Crozet moved from +05 to +04 on 2000-09-01. However, as near as I can make it out that letter was for stamp collectors and I would like something a bit more definitive; quite possibly any 2000-09-01 change merely altered the law to match already-existing practice.
