Cron builder
Cron: every 15 minutes — */15 * * * *
Four runs an hour, at :00, :15, :30 and :45 — */15 expands to exactly those minutes. Like every step expression it is anchored to the clock face, so "every 15 minutes starting from 9:07" is not what you get.
If you do need an offset — say to dodge the :00 rush when every other job on the box fires — give the step a range: 7-59/15 runs at :07, :22, :37 and :52. Same cadence, empty lane. The builder below writes either form for you.
