Well what format should be used then?

The application works like this. Users use a watch time how fast they run
from point A to point B. Afterwards they enter the time taken, say 5 minutes
39 seconds, into a field. The field already checks to make sure the time is
entered in the correct format. After that it takes the time entered in that
fields an enters it into a the db.

So what other field would you enter this into in the db?
