JSI Tip 7525. How do I set the Time Zone from the command line?

To set the Time Zone from the command line, use:

where is the data value of the Display Value Name, or the Std Value Name ,at HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrent VersionTime Zones.

You can also use:

Control.exe %SystemRoot%system32TIMEDATE.CPL,,/Z <Display or Std Value>.

Example:

RunDLL32 shell32.dll,Control_RunDLL %SystemRoot%system32TIMEDATE.cpl,,/Z US Eastern Standard Time
