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

Calcite input time zone:

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.
