How to update cell with timer

Hi -

I have created a custom cell that displays a "duration" of time between a start date and end date (public class DurationCell extends AbstractCell<Date[]>). If the end date is null, I would like the duration to "count up," like a stopwatch.

I'm stuck with how to periodically (every second) update the value of that cell. I would prefer to not have to alter the underlying data object every second, but I don't know of another approach.

Thoughts?
