What settings do you have to make in Windows in order to change the system time of the PC from a WinCC Runtime Advanced?

1. Presettings
Note
You use the Windows function "SetLocalTime" to change the system time of the PC. This function needs the "SE_SYSTEMTIME_NAME" authorization. A user with standard rights or an administrator does not have this authorization.

1.1 Enter the term "UAC" in the Windows search bar. Make the settings for the user account control.
Set the notifications about changes to the computer to "Never notify".
