This policy setting allows you to specify the time of day at which to perform a scheduled scan. The time value is represented as the number of minutes past midnight (00:00). For example, 120 (0x78) is equivalent to 02:00 AM. By default, this setting is set to a time value of 2:00 AM. The schedule is based on local time on the computer where the scan is executing. If you enable this setting, a scheduled scan will run at the time of day specified. If you disable or do not configure this setting, a scheduled scan will run at a default time.
