Can you restrict dashboard alerts to certain hours? how?

Hi,

We have alerts set up to notify us that a processor is exceeding the expected cpu usage.

However, during the night we run some batch jobs.  So high usage is expected.  I don't want to get the alerts when the batch jobs are running.  Is there a way to eliminate certain hours from alert firing.  For example, I'd like an alert to fire when  the CPU % utilization is over 50% during the hours of 6:00 AM ET and 11:00 PM ET (i.e. not between the hours of 11:01 PM and 5:59 AM ET.

Thanks.
