The following time zones are obsolete and probably should be removed. See here for explanation.

How to translate "Etc/GMT[+/-nn]"?

See here for a technique how to use Intl to derive the localized equivalent of GMT+/-nn.

Reproduction Steps

1. Scraped a list of canonical time zones from here
2. Compared scraped list of time zones with calcite's t9n files using this.

Reproduction Version

1.10.0

Regression?

No

Priority impact

p3 - want for upcoming milestone

Impact

Fairly minimal. However the following national capitals are currently absent. America/Argentina/Buenos_Aires Asia/Ho_Chi_Minh Asia/Kathmandu Asia/Yangon Europe/Kyiv

Also for the Urumqi the official time zone should be +8.

Calcite input time zone:

[richiecarmichael]

Per IANA, "Asia/Urumqi" is GMT+6 year-round. This wiki page describes how and why both Urumqi Time (GMT+6) and Beijing Time (GMT+8) are observed in the Xinjiang region.

[fendiaoxiaoshuazi]

Hi @richiecarmichael, on the Microsoft Date & TIme settings panel, Urumqi still appears as UTC +8. I think both cases are used, so I only add this comment for your reference.

The changes required by timezone-groups might be breaking, so it might be good to move this one to target our breaking change release. cc @geospatialem

This should be handled by #10289 as it made changes to use consistent, canonical time zones and also maps deprecated time zones to canonical ones. Thus, it should no longer be considered a breaking change.
