getTime( ) Javascript

Question

I have a php date, and i want the difference about php date and today's date. The code is: function countdown(counter, year, month, day, hour, minute, second){
var datePhp = new Date(year, month, day, hour, minute, second); var today=new Date(); var days=0; var hours=0; var minutes=0; var seconds=0; var sumeDays = 0;

    if (datePhp>today){
        var difference=(datePhp.getTime()-today.getTime())/1000;
        days=Math.floor(difference/86400);
        difference=difference-(86400*days);
        if(days==1){
            sumeDays=days*24;
        }
        hours=Math.floor(difference/3600);
        printHours=Math.floor(difference/3600)+sumeDays;
        difference=difference-(3600*hours);
        minutes=Math.floor(difference/60);
        difference=difference-(60*minutes);
        seconds=Math.floor(difference);`
            $("#counter" + counter).html(printHours + ' Hours ' + minutes + '                 Minutes ' + seconds + ' Seconds');

        if (days>0 || hours>0 || minutes>0 || seconds>0){
            setTimeout("countdown("+counter+", "+year+","+month+","+day+","+hour+","+minute+","+second+")",1000)
        }

The code runs, but runs wrong, because always say less than 24 hours. For example, if phpDate is 4/06/2014 09:30 (where 4 is the European day and 6 is June) and today is 2/06/2014 09:30 (where 2 is the European day and 6 is June). The code say that there are only 24 hours to phpDate.

And the code in html is:

  <div id='counter<?php echo $i ?>'></div>
  <script type="text/javascript">
  countdown(<?php echo $i?>, <?php echo $year?>, <?php echo $month?>, <?php echo $day?>, <?    php echo $hour?>, <?php echo $minute?>, <?php echo $second?>);
  </script>

Where are year, month, day, hour, minute and second defined? — bcmcfc, Jun 02 '14 at 08:20
year, month, day, hour, minute and second are defined in php code, and i passed them by a function. Values about var are ok. — mjosee7, Jun 02 '14 at 08:22
@mjosee7 please add the output of `console.log(new Date())` `console.log(datePhp)` to your question, this will help to see the problem, as it may e.g. be a timezone problem. — t.niese, Jun 02 '14 at 08:44

-1

p = new Date('4/06/2014 09:30')
>Sun Apr 06 2014 09:30:00 GMT+0530 (India Standard Time)
n = new Date('2/06/2014 09:30')
>Thu Feb 06 2014 09:30:00 GMT+0530 (India Standard Time)
diff = p.getTime() - n.getTime()
>5097600000
diffHours = diff / (1000 * 60 * 60)
>1416

looks ok for me, 1416 hours from feb 06 to apr 06

I dont understand your code completely, but when i do it with below code I am getting 48 hours which looks good

var datePhp = new Date(2014, 5, 4, 9, 30, 0),
    today = new Date(2014, 5, 2, 9, 30, 0);

if (datePhp > today) {
    var difference = (datePhp.getTime() - today.getTime()) / (1000*60*60);
    document.getElementById('res').innerHTML = difference;
}

Here is a fiddle for the same. http://jsfiddle.net/tQ9jW/

If you can explain why you are doing all these complex things if you just need the difference in time we could look into debugging the code.

Thanks. It is not April and February. It's the difference about two days – mjosee7 Jun 02 '14 at 08:37
Thats why you should not blindly rely on the string parsing capabilities of JS. The OP clearly states which dates `4/06/2014` and `2/06/2014` represents. They are in the format `DD/MM/YYYY` and not `MM/DD/YYYY` – t.niese Jun 02 '14 at 08:38
ok, can you explain the logic you are trying to do, its not clear for me. Looks like you are not just finding difference in hours what is `sumeDays` and why are you doing things like `difference=difference-(86400*days)` – sabithpocker Jun 02 '14 at 08:41
@t.niese Yes sure. I was just doing a quick check in console. – sabithpocker Jun 02 '14 at 08:51
I have this http://www.mundonets.com/contador-javascript.html but, in a table about auction where in each row has a different time. The code runs right, but the days always say less than 24 hours. For example, if phpDate is 4/06/2014 09:30 (where 4 is the European day and 6 is June) and today is 2/06/2014 09:30 (where 2 is the European day and 6 is June) the programm say that we have 24 hours to date, but really is 48 hours – mjosee7 Jun 02 '14 at 09:40
https://developer.chrome.com/devtools/docs/javascript-debugging try to debug it line by line adding breakpoint at first line and going line by line. As i dont understand your logic its easier for yourself to debug. or come to chat http://chat.stackoverflow.com/rooms/17/javascript – sabithpocker Jun 02 '14 at 09:50
