As a result of an order from the Russian Government, Volgograd will move back to Moscow time (UTC+03:00) at 02:00 AM local time on December 27, 2020.
Microsoft plans to release an update to support this time zone change; however, there is insufficient time to properly build, test, and release such an update before the change goes into effect. In the meantime, we recommend that organizations with devices in Volgograd follow the interim guidance below.
Interim guidance Microsoft recommends that users temporarily set the time zone on their devices to “(UTC+3:00) Moscow, St. Petersburg” on December 27, 2020 at 02:00. Selecting this time zone will then reflect the correct local time (Note: events that have occurred in the past, before the update, will not show correctly).
This can be done in one of the two ways:
Select the Windows logo key, type "time zone", and select Change the time zone system setting. From the time zone dropdown, select “(UTC+3:00) Moscow, St. Petersburg” time zone.
Go to Control Panel > Date and Time > Change time zone. From the time zone dropdown, select “(UTC+3:00) Moscow, St. Petersburg” time zone. Click Ok.
We recommend returning time zone settings to “(UTC+3:00) Volgograd” after an update from Microsoft has been released and installed.
