How select time zone in timedate.cpl? (batch command)

[jonno]

What single command (for use in a batch file) will change the PC's
time zone to GMT+10

Is there a line command which will do this directly?

----------

I have started to look at the "Time And Date" control panel but it
doesn't quite do what I want ...

The following command opens the "Time And Date" control panel and
selects the time zone tab. But what do I do to automatically select
the GMT+10 setting and then close the control panel?

rundll32.exe shell32.dll,Control_RunDLL timedate.cpl,,1
