What is the preferred data type for audio/video track length?

Question

The app retrieves audio tracks and uses a service to get the length of the track, in hh::mm:ss format.
since it's formatted as time, but it's not an actual valid time value, I need some sortable representation of the data.

1. What is your recommendation?
2. How can it be sorted/searched/filtered?

thanks

Answer 1

Well, the answer is : using the time dataType... it's an actual time representation field.
