A schedule sets the windows in which an item can be opened. Pick the simplest type that fits.
Daily
A time span every day, such as 09:00–17:00. Good for "working hours only" credentials.
Weekly
Chosen days of the week, each with a time span, such as Monday to Friday 09:00–17:00. A common guard for production keys.
Monthly
Chosen days of the month, such as the 1st from 09:00 to 09:30. Handy for once-a-month tasks like checking a savings account.
Date range
An open-from and open-until pair. Before or after the range, the item stays sealed. Use it for "not before 1 March" letters or handover documents.
Cron
A cron expression with a duration, for patterns the other types can't express. If an expression isn't supported, Atrium tells you when you save it.
Good to know
- Windows use our server's clock in the time zone you choose.
- Changing or removing a schedule is recorded in your audit log.
- Read Time-locked access for how the lock is enforced.
