Timer Filter Tutorial

hi there, is there a way to increase the speed of the timer? So it runs in double or triple time? Better yet, is there a way to set the start time and end time and the timer will adjust its speed accordingly?

I am trying to create a video that captures a business process. The process itself takes about 2 hours and the video only runs for 2 minutes, i would like to add a timer in the video that will show the clock going from 00:00 to 120:00 in 2 minutes. I hope this makes sense?
