Scheduled event execution in servicenow

hi All,

I am thinking a scenario , where i want to process particular events to be processed at particular time and other in different time

ex: lets say all the events created in incident should be processed when at 3 to 4 and all the events created in change should be btw 5-6 ...

i.e, event should be created and it should be processed later, is there any way for that ???

i tried few options , they are not useful..
