JavaScript Modulus not working consistently

[jerdonald]

javascript forum,

I'm running a timer in my program and want to perform something at 10
second increments using the following code.

  function timer()
  {
   current = (+new Date() - startTime) + runningTime;
   seconds = ((current)/1000);
   minutes = Math.floor((current)/60000)%60;
   if(seconds%10 == 0)
   {
    ex+=1; setenabled();
   }
  } // end function inBoxTimer()

I display the time and can see 10.0, 20.0 etc. show up but it only gets caught
once in a while. I have tried every suggestion on the internet with no luck.

Any Suggestions?

Is there a reason why you aren't using setInterval to do something every 10 seconds?

Like this:

setInterval(function() {
  //do something
}, 10000)

Johna,
Thanks for the reply.

The clock is a running time that can be stopped and re-started by the operator several times so it's not a regular interval. If I change the code to read:
if(seconds == 10) it will work every time?
