I'm trying to create a report that provides counts of tickets resolved within "bands" of time.

Eg.

Count of requests resolved within 1 hour

Count of requests resolved within 6 hours

Count of requests resolved within 1 day

Count of requests resolved within 2 days

Count of requests resolved within 1 week

Count of requests resolved > 1 week

It's a pretty standard Help Desk report, but I can't figure out how to make it with the tools available. Can anyone tell me how to do this?

Cheers,

Sean
