Eric Smith from GWI has shared his admin hack for having a process happen after only five minutes.
“Challenge: Process Builder time lapse intervals can only be expressed as a whole number of hours or days. How can I kick off an action after only 5 minutes?
Hack: Create a formula field with a time offset and base your elapsed time on the new formula field.
Example: New formula field for 55 minutes ago:
NOW() - 55*(1/24/60) /* fraction of a day in minutes */
Implement: In Process Builder set the elapsed time to be 1 hour after your formula field for 55 minutes ago.”
