Count Up Timer?

I’d like to add a counter to a site that basically advances one number every day to be reflected in a safety graphic of “Days Without Accident”. I suspect that the difficult work is already included in the countdown timer function but it isn’t currently an option for it to count AWAY from a date, only toward. And ideally you’d be able to have an output option of “ddd” which would give you up to 999 days without accident.

Maybe an option for v5? I have found a site that produces a code to embed but would prefer something more self contained. Any other options?

Good suggestion thanks.
