Specify arbitrary start and end times for cron job

Question

For Quartz Cron, is it possible at all to specify a cronexpression that corresponds to:

Run every 6 minutes, starting from 9:12 AM until 5:37 PM.

I attempted to write the cronexpression 0 12-37/6 9-17 ? * * but this does only runs once an hour. I also understand that the cronexpression 0 /6 9-17 ? * * corresponds to Run every 6 minutes between the hours of 9 AM and 5 PM.

But is there any way to constrain the starting and ending minutes on that cronexpression? More generally, can I specify an arbitrary start and end time with the job in question running every n intervals of time?

Answer 1

You can do it with 3 cron strings:

0 12-59/6 9 * * *
0 /6 10-16 * * *
0 0-37/6 17 * * *

Give them all the same task to run.
