cron expression

[Elif Alverson]

Hello, 

I am trying to create a JIRA issue every three months on day 21st and using 0 8 21 3,6,9,12 * on the scheduler. However it says " Incorrect cron expression!".

What is incorrect in here?

Thanks!

That isn't the correct count or alignment of fields for the documented syntax.  The first number is seconds.  You're telling it to run at 21:08:00 on the 3rd, 6th, 9th, or 12th of every month.  You also need to specify ? instead of * for the day-of-week field to say that you want to ignore it.  These are differences from the traditional UNIX cron syntax, but they documented both by Atlassian and by Quartz.

The cron expression you want is: 0 0 8 21 3,6,9,12 ?
