If you want to automate check/change of timezone on Windows Server 2008 or greater; this article is for you

to check the current timezone: tzutil /g

to change the current timezone: tzutil /s “Romance Standart Time”

Reference for Timezones: http://msdn.microsoft.com/en-us/library/ms912391(v=winembedded.11).aspx

however tzutil does not contain remote option. To bypass this limit, you can use the invoke-command using powershell

to check the timezone on remote computer: invoke-command -cn computername -command {tzutil /g}

to change the timezone on remote computer: invoke-command -cn computername -command {tzutil /s “Romance Standard Time”}
