Scheduling a cron job

Does anyone know off hand if I can set a cron job to run at 8:30 A.M. server time with the following config or would the job run every 30 minutes during every 8th hour in 24?

30 - minutes
8 - hours

    • day of the month
    • month
    • day of the week

The way you have it should run every day at 8:30am. In order to run every 30 minutes of each 8th hour, I believe you’d need something like:

30 - minutes
*/8 - hours

    • day of the month
    • month
    • day of the week

Amazing enough, the settings below run the job every minute starting at 8:30 AM server time.

I wish I could get it to run just once and only once at 8:30 AM everyday.

Got any ideas?

30 - minutes
8 - hours

    • day of the month
    • month
    • day of the week

I have been reading up on as much as I can find about scheduling cron jobs and it would appear that the job was scheduled correctly to run at 8:30 AM server time.

Why it was running every minute after 8:30 is not something that should have been happening. I will open a support ticket.
