Maybe easiest way is use big int type in duration field and store duration time in milliseconds

I don't see the difference between interval and "time as duration". If I have following records Place: place1 Duration: 00:00:10 Place: place2 Duration: 01:30:40 Place: place3 Duration: 20:00:00 I need the output place1 - 21:30:50.
