The commentary in 'africa' says Crozet can use TZ='Indian/Reunion', so we don't need a separate Zone entry for the Crozet Islands. If this isn't correct please let us know the details.
Hmmm, at least T&D says Crozet is UTC+5 while TZDB says UTC+4. Which is in error? https://www.timeanddate.com/worldclock/france/ile-de-la-possession-crozet-is... If UTC+5, then it would align with Indian/Kerguelen I think. Geographically and politically, this seems to make more sense than Indian/Reunion. Can't seem to find an authoritative reference. -Matt ________________________________ From: tz <tz-bounces@iana.org> on behalf of Paul Eggert <eggert@cs.ucla.edu> Sent: Monday, March 19, 2018 4:05 PM To: REMI ACIEN; Time Zone Mailing List Subject: Re: [tz] [PATCH1/1] Propose new zone for Crozet Islands On 03/19/2018 01:33 PM, REMI ACIEN wrote:

I asked a French-speaking friend to look into this, and he said tzdb appears to be correct, at least as of 2014. He inferred Crozet's UTC offset from this blog: http://www.taaf.fr/Journal-de-bord-du-Marion-Dufresne-Novembre-2014-OP3

"Samedi 15 novembre 2014 ... Tiens, pour revenir sur terre, à minuit on change de fuseau horaire : +1. Surtout ne pas oublier, histoire de ne pas rater le petit-déjeuner. ... Petite annonce : dans la nuit on change de fuseau horaire (avancer les montres d’une heure – temps universel + 5) donc la nuit sera plus courte. ..." states UTC+5 so assuming that is correct Indian/Kerguelen which is also in the antarctic part of the French TOM Territoire d'Outre-Mer TAAF Terres Australes et Antarctiques Françaises (ISO 3166 TF gTLD .tf) https://en.wikipedia.org/wiki/French_Southern_and_Antarctic_Lands https://www.cia.gov/library/publications/the-world-factbook/geos/fs.html https://www.cia.gov/library/publications/the-world-factbook/graphics/maps/fs... makes sense, although the permanently populated administrative centre in Indian/Reunion is closer in longitude! These sites seems to have the same opinion: https://www.annuaire-mairie.fr/mairie-archipel-des-crozet.html#geographie https://www.citipedia.info/region/general/French+Southern+Territories_Crozet... https://www.citipedia.info/region/general/French+Southern+Territories_Crozet https://www.horlogeparlante.com/heure-archipel-des-crozet-terres-australes-e... and mention Indian/Kerguelen. However this site differs: http://ilescrozet.blogspot.ca/2014/10/photo-de-la-semaine-44.html "lundi 27 octobre 2014 Photo de la semaine 44 Ce week-end la France métropolitaine est passée à l'heure d'hiver. Le décalage horaire entre Paris avec La Réunion et le district de l'Archipel de CROZET est donc de 3 heures en moins pour la métropole." stating 3 hours difference from the capital in winter. I ignored sites saying Reunion or Crozet were UTC+3 or Paris+2, or Paris+3 with no date. Searching for fuseau horaire Archipel Crozet eliminates a lot of the hits otherwise shown for Crozet, FR and Crozet, VA. -- Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada

Please paste the actual links - both of your quoted links give me 404s. They appear to be redirected and may work only with a MS account. Time zone info is shared by MS on this list, or comes from this list, often from those who run time zone sites, and monitor time zone announcements. Searching on this list, its IANA archive, or a web archive of the list, for zones in which you have an interest, will show you relevant published info, decisions, and changes made to the time zone db. -- Take care.
