If I set a CRON at these times (on two different scripts)

0 09 * * * * - 9AM
0 21 * * * - 9PM

Will this work correctly. I believe it will but I can not make an error here so I just want some comfirmation. Thanks.

Andy,
Are you asking if the cron is correctly stated or will the script work being called twice. Im not sure I understand your post.

You have it correct. The only problem i see, is 1 extra * in the first one.

Othe than that, you have it set up correctly if you are looking for 9am and 9pm

Regards
