Let’s say you have a field [Event Duration] that shows duration of some event in seconds, and, instead of displaying it as, say, 5,000 sec, you want to format it in hours/minutes/seconds, as 1 hr 23 min 20 sec
Step 1: Create a date field: DateAdd(“second”, [Event Duration], Date(“1970-01-01”))
Step 2. Set the formatting for this field as a custom format: %H:%M:%S
