I am wondering if there is a simple way to displaying time elapsed as is it is happening. Instead of getting the date time at start and subtracting from datetime at end. I am looking for a 00:00:00 format as in hrs:min:sec. I thought about maybe adding a timer and somehow converting the milliseconds into the others. Or same with using the stopwatch class.

My main issue is displaying it in the 00:00:00 format as it happens.
