By default, Security policy rules are always in effect (all dates and times). To limit a Security policy rule to specific times, you can define schedules, and then apply them to the appropriate policies. For each schedule, you can specify a fixed date and time range or a recurring daily or weekly schedule. To apply schedules to security policies, refer to Policies > Security.
