SDP Create Time Report: Using specific times

Is anyone able to help, have been tasked to provide a twice daily report showing generated requests created in a 12 hour window.  First from 07:30 ending at 19:30, the second 19:30 to 07:30 the following day.
Advanced matrix doesn't allow so now looking at query editor which is beyond me.
