How to work the timezone using PowerShell?

To get the timezone of the System, you can use the Get-TimeZone command.

DisplayName                : (UTC-07:00) Mountain Time (US & Canada)
StandardName               : Mountain Standard Time

To Set the TimeZone of the System, you can you the ID or the Name of the timezone.

Example

PS C:\> Set-TimeZone -Id "Pacific Standard Time" -PassThru
Id                         : Pacific Standard Time
DisplayName                : (UTC-08:00) Pacific Time (US & Canada)
StandardName               : Pacific Standard Time
