timer function

[Darren Showers]

I'm running a timer function that counts down from set time frames. It has
an odd tendency to drop 2 seconds at the beginning but then work fine the
rest of the way. Can anyone suggest what could be happening here?

What is happening here is that you don't show us the code.

Thank you for the unnecessary candor. Here is the code:

function startTimer() {
running = true;
var now = new Date();
start =now.getTime();
var seconds = getSec();
var setTime = 1000 * seconds;
endTime = start + setTime;
showCountDown()
}

function getSec() {
var r = document.frm.radio1;
for (var i=0; i<r.length; i++) {
if (!r.checked) continue;
else return r.value;
}
return null;
}

function showCountDown() {
var present = new Date();
moment = present.getTime();
if (endTime - moment<= 0) {
stopTimer();
displayTimer.innerHTML = "TIME'S UP!";
showTimeOver();
} else {
var lapse = new Date(moment - start);
var minLapse = lapse.getMinutes();
var secLapse = lapse.getSeconds() + 1;
var timeLapse = minLapse;
timeLapse += ((secLapse < 10) ? ":0" : ":") + secLapse;
document.frm.timeLapse.value = timeLapse;
var delta = new Date(endTime - moment);
var theMin = delta.getMinutes();
var theSec = delta.getSeconds();
theTime = theMin;
theTime += ((theSec < 10) ? ":0" : ":") + theSec;
document.frm.timerDisplay.value = theTime;
displayTimer.innerHTML = theTime;

if (running) {
timerID = setTimeout("showCountDown()",1000)
}
}
}

function stopTimer() {
displayTimer.innerHTML = theTime + " TIMER STOPPED";
clearTimeout(timerID);
running = false;
}
