So what I am asking is, there a date and time formats, that handle what date it is or what the clock time is. But is there a type in SQL that deals with measured time, so that is measured units of time.

So for example car a took 1:21:30 (mm:ss:hundredths) for lap two, which can be saved and then compared to his/her previous lap and others lap times. Of course in a business environment this would be an handle time (time on call) in a call centre etc.

Lots of potential uses but how is it implemented and used?
