Pacific/Bougainville is incorrectly matched to Papua New Guinea Time

[Zooce]

Pacific/Bougainville is UTC+11 and should be Bougainville Standard Time, but somehow is matched to Papua New Guinea Time which is UTC+10.

Perhaps this is just based on older data? I'm making this random assumption because I was browsing through the CLDR 47 release and I did see this in common\supplemental\windowsZones.xml:

<!-- (UTC+11) Bougainville Island -->
<mapZone other="Bougainville Standard Time" territory="001" type="Pacific/Bougainville"/>

I should note that I first noticed this in the results of TZNames.GetNamesForTimeZone("Pacific/Bougainville", "en-US").

Any ideas?

BTW, thanks for this package, it's amazing!

Thanks for bringing this up. This is due to the metadata field in CLDR here:

https://github.com/unicode-org/cldr/blob/1ad583f6e1a33c0bc820706021e72484e55017c2/common/supplemental/metaZones.xml#L1421-L1423

It has expired, but this library is not yet taking the from or to fields into account. I just wrote that up as #117 and will try to find time to address this oversight. Thanks.

Ah, I see it now.

Yep. Sorry about the oversight. Many years later and someone finally noticed! 😅
