There have been a lot of requests for a built-in timer/ stopwatch feature:

Timers cant wait> I have a task management app. I would like to> Stopwatch Feature

Others have created samples that add/edit rows to measure a duration:

Simulate a Timer in your app

But there’s no live countdown (or count up) on the screen.

This sample app uses a different approach, to create a live countdown:

The timer sheet just stores the duration, and a name for the timer.

The URL parameter start=### can be used to start the video at any point.

It’ll be even more useful when the new iframe view is released. It’s a little clunky switching back and forth to the browser/ Youtube, but in an iframe this will be a decent solution for timers. I imagine you could have an action to ‘reset’ the iframe and start the timer over.
