A schedule is an entity that defines a set of time constraints that can be applied to a multitude of situations in the system. Each time constraint is defined by a date coverage (daily, weekly, ordinal, or specific) and a time coverage (all day, fixed range, daytime, and nighttime).
Each time constraint is characterized by a date coverage (date pattern or specific dates covered by the schedule) and a time coverage (time periods that apply during a 24-hour day).
When the Security Center Directory is installed, the Always schedule is created by default. This schedule has a 24/7 coverage. It cannot be renamed, modified, or deleted, and has the lowest priority in terms of schedule conflict resolution.
Time zones for schedules
By default, the time of day for a schedule is based on the local time zone set in each individual context where it is applied. For example, if the schedule is used to set continuous video recording from 9 a.m. to 5 p.m., whether the video unit is in Tokyo or London, the recording occurs on schedule according to the local time. This is because every video unit has a time zone setting to control video settings and recordings relative to the unit’s local time.
When a schedule is applied to an entity that has no time zone settings, such as the logon schedule for a user, the local time is taken from the server hosting the Directory role.
