You can now create a schedule in Process Builder that waits for zero
hours or days, which means the pending actions are executed as soon as possible. Previously,
one hour was the minimum time for a pending scheduled action that’s adjusted from the current
time. You can use scheduled actions to avoid governor limits, because scheduled actions are
executed in a separate transaction from immediate actions.
Where: This change applies to Lightning Experience and Salesforce Classic in Essentials,
Professional, Enterprise, Performance, Unlimited, and Developer editions.
How: When you add a schedule to a process, set the time for actions to execute to
0 Hours from now.
