This topic provides details of how to update system time. You can adjust system time using a time adjustment, which is the preferred method, or manually change the system time using the time of day system value, if you need to change the system time immediately.
If your system time is not correct or jobs are running with the wrong time, you might need to adjust or change the system time. The time adjustment method is the preferred method for changing the system time unless you need to change the system time more than two hours.
