The timer service selects a random time within the window of execution interval to start the job on each applicable server.
This capability helps to reduce the overall load of resource-intensive timer jobs that run on multiple servers on the farm.
For every job that you schedule, you specify when the timer job will run, specified in a 24-hour time format.
You must specify the time in local time instead of as an offset from Coordinated Universal Time (UTC). By default, daily, weekly, and monthly schedules also include a window of execution.
