The time window is the period of time during which a job can begin. The time window does not extend beyond 23 hours, 59 minutes, and 59 seconds. For example, you cannot set a time window to start at 03:00 AM and end at 05:00 AM the next day.
The default time window is from 11:00 PM to 10:59:59 PM. If you use the default setting, a job that is scheduled to run on Monday can begin at or anytime after 11:00 PM on Monday. It cannot start after 10:59:59 PM on Tuesday night.
You can set a time window that extends past midnight and into the next day, which may change the day on which the job runs. For example, if you schedule a job to run every Friday between 10:00 PM and 04:00 AM, the job may run on Saturday before or at 04:00 AM. If you do not want the job to run on Saturday, you must alter the time window to start the job no later than 11:59:59.
