Finding records within 15 minutes from now?

I'm struggling with the php or mysql query to find records within my database that are within 15 minutes from now and prior. Example: It's 2:30pm on 4/12/05 I need to find all records with a RecordTime of 2:45pm and previous. So it should find: rec1 time: 2:45 date: 4/12/05 rec2 time: 2:00 date: 4/12/05 rec3 time: 1:30 date: 4/8/05 etc. It would not find: rec4 time: 3:15 date: 4/12/05 rec5 time: 4:00 date: 4/23/05 Make sense? I'm reviewing the manuals for datediff, curdate and other functions but nothing seems to be making sense for what I need. Any ideas?
