How to change Timezone in Windows from Command Line

Guys, today let us learn how to change and/or update the Timezone on Windows machines without using the GUI i.e from the command line. On most flavors of Windows, the timezone utility (tzutil.exe) lies at C:\Windows\System32 location. 

Note : Updating timezone requires a user to have administrator rights. Make sure you have it.

So now, open the command line as administrator. Open the tzutil.exe from C:\Windows\System32 location. Let us look into a few illustrations on its usage.

• To list current time zone :

C:\Windows\System32>tzutil.exe /g

Eastern Standard Time

• To display the list of all available time zones :

C:\Windows\System32>tzutil.exe /l

(UTC+08:00) Irkutsk
