Now it's 3/12/2018 3:02:13 PM.

I have a cron expression 0 0 0/7 * * ? (every 7 hours starting at 00 am, of every day). As a result, executions:

 1. 3/12/2018 9:00 PM
 2. 3/13/2018 12:00 AM
 3. 3/13/2018 7:00 AM
 4. 3/13/2018 2:00 PM
 5. 3/13/2018 9:00 PM
 6. 3/14/2018 12:00 AM
 7. 3/14/2018 7:00 AM

As you can see, there were 3 hours between 1st, 2nd and 5th, 6th runs. Not 7.

Is it possible to make the rules run at the correct time, like this?

 1. 3/12/2018 9:00 PM
 2. 3/13/2018 4:00 AM
 3. 3/13/2018 11:00 AM
 4. 3/13/2018 6:00 PM

    Title aside, what's this got to do with Java? – Mena Mar 12 '18 at 13:34

    This cron does what you told it to: starting from 0:00 every seven hours (which *will* have jumps, because 24 is not a multiple of 7). – M. Prokhorov Mar 12 '18 at 13:54

You are not starting "every 7 hours starting at 00 am" - you are starting in intervals of 7. I think. You should have a look at the documentation at https://help.ubuntu.com/community/CronHowto or the examples at http://www.baeldung.com/cron-expressions
