+> Interval run schedules are based on UTC time using a cron-style system. This means the next run time aligns with the nearest UTC interval, which may differ from your local time. For example, if you set a 24-hour interval at 4 PM PST, the next run aligns with 12 AM UTC, which occurs at 5 PM PST. If you set it after 5 PM PST, the next run occurs the following day at 5 PM PST.

 You can also click **Run Now** on the Audience Overview page at any time (even if the run schedule is **Interval** Overview **Day and time**) to manually trigger a run on your warehouse and send data to enabled destinations.
 
 There may be up to a five minute delay from the configured start time for audiences that are configured with the **Interval** and **Day and time** run schedules. For example, if you configured an audience with the **Day and time** compute schedule to run on Mondays at 8am, it can compute as late as Monday at 8:05am. This is to help us better manage our system load.

-> When configuring an interval run schedule, the system uses a cron-based mechanism anchored to UTC, meaning the next run time aligns with the nearest UTC-based interval cycle, which may shift the schedule relative to your local time zone.
-> When you set a 24-hour interval run schedule at, for example, 4 PM PST, the cron-based system using UTC schedules the next run for 5 PM PST the same day, as it aligns with 12 AM UTC; however, if set after 5 PM PST, the next run will be at 5 PM PST the following day.
+> info "Execution timing"
+> Linked Audiences don’t schedule the next run until the current one finishes. For example, if you set a 15-minute interval but the workflow takes an hour to complete, the next run won’t start until that hour-long run ends. After it finishes, Segment calculates the next run time based on the next available interval.
