That would agree with my own experience of the system. On one occassion I found after running the script that the timezone and language settings had applied but the date format setting hadn't. When I logged in on the test account to check it had worked I recieved an error message that the date format (which was still set to m/d/yy I think) wasn't compatible with my other regional settings. A few minutes later the date format had setting had taken and everything was fine. The nature of the cloud I guess.
