Cron expression to run job every 3hrs and 15 mins

Question

I need a particular job to be run every 3hrs and 15 mins .

Will this expression serve my purpose ?

batch.backupscores.cronExpression=0 0/15 0/3 * * ?

thanks in advance .

Answer 1

No, this expression won't work and I believe you can't express this using Cron. But you can use simple trigger instead.

Running job every 195 minutes will work (3 * 60 minutes + 15).

Answer 2

0 15 0,3,6,9,12,15,18,21 * * ?

this will serve the purpose
