No, you need to use a Time exception for unwanted times, but in this case it is much easier to create a Custom Time Trigger.
By Custom time trigger, I would have to specify hours and minutes.
If I wish to run it every 15 minutes, between hours 9am-4pm, I would have to check off minutes 3, 18, 33, 48. However, that will lead to the job starting up at 9:03am no?
If I were to create a time exception, would I use hours between 4PM to 9AM with minute set at 49 to ensure that it runs at 4:48PM and 9:48AM?
Thank you.
