Changing time zone with command prompt and PowerShell

Last tested with win10 21H1. Who knows if it’ll work tomorrow.

Text you’ll skip

If you’re getting errors with time zones not saving (this could be a GPO issue) when changing in the UI and the old way with timedate.cpl you can try with command prompt or powershell.

cmd

List time zones with tzutil /l. This will list every time zone.

tzutil /l

Copy the value on the second line. In the example below the time zone name is Central Standard Time
(UTC-06:00) Central Time (US & Canada)
Central Standard Time
You can set the time zone with the time zone name using tzutil /s “<time zone>”

tzutil /s "Central Standard Time"

PowerShell

Get- and Set-TimeZone are the powershell equivalents.
Get a list of all time zones with Get-TimeZone -ListAvailable

Get-TimeZone -ListAvailable

You can filter results with the usual PS tricks.

Get-TimeZone *central*

Once you have the time zone ID you can set it with Set-TimeZone.

Set-TimeZone "Central Standard Time"
