Question

Answer 1

+1 A:

First, you can always grab the current time by

var currentTime = new Date();

Then you could check out this "pretty date" example at http://www.zachleat.com/Lib/jquery/humane.js

If that doesn't work for you, just google "javascript pretty date" and you'll find dozens of example scripts.

Good luck.

Answer 3

+4 A:

Try something like this

// record start time
var startTime = new Date();

...

// later record end time
var endTime = new Date();

// time difference in ms
var timeDiff = endTime - startTime;

// strip the miliseconds
var timeDiff /= 1000;

// get seconds
var seconds = Math.round(timeDiff % 60);

// remove seconds from the date
timeDiff /= Math.round(60);

// get minutes
var minutes = Math.round(timeDiff % 60);

// remove minutes from the date
timeDiff /= Math.round(60);

// get hours
var hours = Math.round(timeDiff % 24);

// remove hours from the date
timeDiff /= Math.round(24);

// the rest of timeDiff is number of days
var days = timeDays;

Hi,

Hope this will help:

<!doctype html public "-//w3c//dtd html 3.2//en">
<html>
<head>
<title>compute elapsed time in JavaScript</title>
<script type="text/javascript">
function display_c(start){
window.start = parseFloat(start);
var end = 0 // change this to stop the counter at a higher value
var refresh=1000; // Refresh rate in milli seconds
if(window.start >= end ){
mytime=setTimeout('display_ct()',refresh)
}
else {alert("Time Over ");}
}

function display_ct() {
// Calculate the number of days left
var days=Math.floor(window.start / 86400);
// After deducting the days calculate the number of hours left
var hours = Math.floor((window.start - (days * 86400 ))/3600)
// After days and hours , how many minutes are left
var minutes = Math.floor((window.start - (days * 86400 ) - (hours *3600 ))/60)
// Finally how many seconds left after removing days, hours and minutes.
var secs = Math.floor((window.start - (days * 86400 ) - (hours *3600 ) - (minutes*60)))

var x = window.start + "(" + days + " Days " + hours + " Hours " + minutes + " Minutes and " + secs + " Secondes " + ")";


document.getElementById('ct').innerHTML = x;
window.start= window.start- 1;

Answer 5

+1 A:

Something like a "Stopwatch" object comes to my mind:

Usage:

var st = new Stopwatch();
st.start(); //Start the stopwatch
// As a test, I use the setTimeout function to delay st.stop();
setTimeout(function (){
            st.stop(); // Stop it 5 seconds later...
            alert(st.getSeconds());
            }, 5000);

Implementation:

function Stopwatch(){
  var startTime, endTime, instance = this;

  this.start = function (){
    startTime = new Date();
  };

  this.stop = function (){
    endTime = new Date();
  }

  this.clear = function (){
    startTime = null;
    endTime = null;
  }

  this.getSeconds = function(){
    if (!endTime){
    return 0;
    }
    return Math.round((endTime.getTime() - startTime.getTime()) / 1000);
  }

  this.getMinutes = function(){
    return instance.getSeconds() / 60;
  }      
  this.getHours = function(){
    return instance.getSeconds() / 60 / 60;
  }    
  this.getDays = function(){
    return instance.getHours() / 24;
  }   
}

Answer 6

+1 A:

Try this...

function Test()
{
    var s1 = new StopWatch();

    s1.Start();        

    // Do something.

    s1.Stop();

    alert( s1,.ElapsedMilliseconds );
} 
    // Create a stopwatch "class." 
    StopWatch = function()
    {
        this.StartMilliseconds = 0;
        this.ElapsedMilliseconds = 0;
    }  

    StopWatch.prototype.Start = function()
    {
        this.StartMilliseconds = new Date().getTime();
    }

    StopWatch.prototype.Stop = function()
    {
        this.ElapsedMilliseconds = new Date().getTime() - this.StartMilliseconds;
    }
