I would like to run cron job A every 3 minutes, and cron job B every 5 minutes. But I would like job A to always run 3 minutes before job B.

How would I accomplish this?

?? - job A0 run at 0h12, job B0 would run at 0h15, but then job A1 would run also. – Archemar Feb 21 '18 at 06:25

Is this a trick question? – Michael Hampton Feb 21 '18 at 07:50
@MichaelHampton I wish I had to the time for that... – Gaia Feb 21 '18 at 14:46
@Archemar, right, hence the need to sync them. – Gaia Feb 21 '18 at 16:11
I asked a more specific question, but my challenge is to make job A run before job B. i can't put the two together because B needs to finish in less than 30 seconds, and A takes a little over a min to finish – Gaia Feb 21 '18 at 16:12
what about jobA ; jobB with a semicolon ? – Archemar Feb 21 '18 at 16:45

You might want to take look at some of the mechanism's I use to deal with irregular cron schedules - let both A & B use the same flock and you prevent running the batches concurrently. Record the last successful run of A and don't start B until the minimum interval has passed. – HBruijn Mar 15 '18 at 14:31
