The first hurdle is privileges - yes, you do need admin rights, and maybe an elevated CMD shell even if you're an admin. This is for a reason, system time is an admin function and should not be changed by regular user accounts.

Why do you need to change the system time configuration?

If you get past the privileges issue:
- you should not need to stop or start the service, just /configure, then /update, then /resync
- make sure your syntax is correct, there seem to be some errors in your sample code above
