duration

The length of time that alarms remain muted when the schedule activates. The duration must be between 1 and 50 characters in length.

Specify the duration using ISO 8601 duration format with a minimum of 1 minute (PT1M) and maximum of 15 days (P15D).

Examples:

• PT4H - 4 hours for weekly system maintenance

• P2DT12H - 2 days and 12 hours for weekend muting from Friday 6:00 PM to Monday 6:00 AM

• PT6H - 6 hours for monthly database maintenance

• PT2H - 2 hours for nightly backup operations

• P7D - 7 days for annual company shutdown

The duration begins when the schedule expression time is reached. For recurring schedules, the duration applies to each occurrence.
