iOS animation flicker

Hello,

I have a simple timer that updates every 1/10 of a second using setTimeout

/**
        *
        *    Calculates the time elapsed in milliseconds and displays
        *    the total elapsed
        *
        */
        showElapsed: function(){
            if (me.isStarted){
                var lastStart = me.getCurrentStartStop();
                var stopTime = lastStart.stop || new Date();
 
                var elapsed;
                if ((lastStart.stop == null)&&(me.isWindowFocused)){ 
 
            // clock is running
            elapsed = me.timeMeta.elapsed + (
                stopTime - lastStart.start.getTime()
            );
                    setTimeout(me.showElapsed, me.refreshInterval);
                }
                else{
                    elapsed = me.timeMeta.elapsed;
                }
                me.displayTime(elapsed);
                me.removeWindowEvents();
            }
        },

and the caller

var displayTime = function(ms) {
    // use moment.js to format time
    $.lblTime.text = moment.utc(ms).format("HH:mm:ss.S");
 
    // after 1 minute, just refresh every second
     if (ms > 60000){
         stopWatchHelper.displayTime = function(ms){
             stopWatchHelper.refreshInterval = 1000;
             $.lblTime.text = moment.utc(ms).format("HH:mm:ss");
         };
     }
};

On each call, it will update a label text with the time transpired.

The problem is, compared to the execution in Android, there is a horrible amount of flicker.

I was wandering if there were any tips on how to reduce this flicker

Thanks,

David
