Windows Server Change Time Commandline

Ever join a server to the domain and forgot to change the time zone beforehand, then the Time Zone GUI change options are greyed out? There's a way around that using either a command line option or via PowerShell.

Option1: Invoke CMD as administrator
tzutil /g (displays current time zone)
tzutil /l (displays all time zone options)
tzutil /s "Central Standard Time" (sets time zone)
tzutil /g (to verify change)

Option2: Invoke Powershell as administrator
Get-TimeZone
Get-Timezone -ListAvailable
Set-Timezone -Id "Central Standard Time"
Get-TimeZone
