Change refreshRateMS while countdown is running

[NoSoup4you2]

I am wondering if there is an option to change the refreshRateMS while i run the countdown ?
In my case i have a game clock which will count down from 20 Minutes in sec intervals so i start the
clock with a refreshRateMS = 1000 then i would like when my onAlmostDone event fires the refreshRateMS = 100 which in my case is the last 60 sec. Hop there is a way to do this or does this require to stop countdown, set new values and then start again ?

That's an interesting question (i'm a bit out the javascript game lately)
You could try directly changing the refreshRateMS on the stopwatch.

myCoolStopwatch.refreshRateMS = 100;

But I don't know that it will work. It's an interval timer, I'm not it automatically start triggering at the new time.

But this should work:
myCoolStopwatch.stop();
myCoolStopwatch.refreshRateMS = 100;
myCoolStopwatch.start();

At worst you'll lose a millisecond.
