Hi tikmads,

As maciep states it would be easiest to schedule two alerts. Just create one alert, clone it, then alter the cron schedule. You could also use a report for the alert search allowing you to change the saved search (report) in one place.

The cron syntax is:

 0 7-19 * * 1-5  (run hourly, 7am-7pm inclusive, Mon-Fri) 
 0 7-16 * * 6  (run hourly, 7am-4pm inclusive, Saturday)

There are plenty of cron websites out there and Splunk's cron documentation can be found here
http://docs.splunk.com/Documentation/Splunk/6.2.5/Alert/Definescheduledalerts#Use_cron_notation_for_...

It would be possible to have just one alert and then use the search to filter out results based on day and time etc. Look here for an example: http://answers.splunk.com/answers/180682/how-to-write-a-cron-schedule-for-a-single-alert-to.html
Doing this may potentially add unnecessary complication to your search however, and run searches when it's not necessary to.

Hope this helps.
