If I read correctly the tz data for French Polynesia, there are three tz zones that are half an hour apart. I searched for an independent confirmation, but I can't find any evidence that FP has multiple local times. The best I have found so far is

<http://www.outre-mer.gouv.fr/outremer/front?id=outremer/decouvrir_outre_mer/polynesie_francaise/publi_P_vie_pratique___decalage_horaire_1125327034760>

which suggests that all of FP is in a single timezone.

Any idea of the source of the current data?

Thanks,

Eric.
