Passing Server Time - Countdown Timer That Currently Uses The Client's System Time To Calculate The Countdown
Feb 4, 2011
I'm using a javascript-based countdown timer that currently uses the client's system time to calculate the countdown. I assume that this line of code is where this is performed:
Code:
I'm trying to make the script use server time instead as some people may have wrong dates/times set or live in different time zones etc.
So what I did was use a bit of php:
PHP Code:
This gives a result but now the countdown is 30 days off. I am testing on my local xampp server (which also uses system time) so there should be no discrepancy. I also tried adding
Code:
But no difference.
I can post the whole script if required but it is reasonably long.

I own a GPT site that offers member Daily SUrveys. When a daily survey is completed, the time of completion is stored in SQL in Unix time format. I hired a guy to code a Countdown timer for me that would be placed next to every completed offer in member's panel and that would show how much time is remaining till the Daily surveys resets and becomes available to the member for completion again(Daily Surveys reset every 24 hours)

I found the below script that works fine for the actual countdown, but when the user refreshes the page, the countdown starts from 5 minutes again.
What I am trying to do, is handle users that put something in their shopping cart and then get side tracked or what ever reason and that same product then being purchased by another person when I only have 1 left.
So using PHP I am going to subtract the qty of that product by 1 and then I want the website to either put it back, if the users checkout times out, or if a normal process it is taken out permanently.
So long story short I think I need some sort of 'memory' for the javascript, so the user can't just keep refreshing and it starting from 5 minutes each time. Also it needs to be carried through to other pages.

I do have the countdown script (see link below) to display the time between current time and the date given in real-time. However, I want to achieve to display the time difference between a given start and end time. Right now, it calculates from the current server time to the end time. I want to be able to set up my own start time and end time.

Im putting together a pair of countdown timers that need to restart every 24 hours. One restarts at noon and the other at midnight. Im using Keith Woods plugin @ [URL]
So far I have been able to implement his serverTime function to sync to the servers clock and instantiated 2 countdown timers. so far so good.
What I need to do now is 2 things:
1. I need to define today + X hours to countdown to instead of setting a exact date like in this example:
var noonCountDown = new Date();
noonCountDown = new Date(noonCountDown.getFullYear() + 0, 5 - 1, 28, -12);// 2011, May, 28, 12pm
2. Once today is defined dynamically I believe that may just solve the problem and reset the timer. But I may not be thinking clearly here. So I guess Im just wondering if this is how you would go about making the countdown restart upon completion.
Here is my code that Ive got so far:
$(function () {
function serverTime() {
var time = null;
$.ajax({url: 'http://www.localhost.com/projects/countdown/servertime.php',
[Code].....

function ulticountdown(time, id, format, keepCounting, zero, langarray){
timeleft = time;
var countUp = false;
if (timeleft < 0) {

I have looked and looked and looked but i can't find what i'm looking for. I need a progress bar that counts down and shows the time inside the bar as it is counting down. it doesn't have to be fancy it just has to work. what i'm doing now is a periodic update using ajax and then changing the size of a bar in css. it works but it is not ideal. does anyone know where i can find a tutorial for creating a countdown bar? it can be jQuery or just javascript i'm getting half decent at both.

I have been using the jquery countdown plugin made by [url] for a while and while I am pretty familiar with it, I haven't been able to accomplish what I want for one of my projects.
I want to be able to add hours/minutes/seconds to a countdown in real-time by clicking a button.
Let's say I have 2 countdowns. They both get their ending date from a mysql db, e.g: 2010-09-26 00:00:45 and 2010-09-27 14:45:00
When I click a button, I want the countdown Y to increase by the X amount of hr/min/sec, update my ending date in mysql, and update my counter for every visitors to see without having them refresh the page. I have tried messing with ajax, but wasn't able to accomplish anything close. (I got it to update every 1 sec but it would flicker then)

I am having a problem trying find out how to turn a number of seconds into a 00:00 format to do a countdown, and when it reaches 0:00 to redirect the window...
here is what I have figured out:
Code:
var tID = 0;
var startTime = null;
var timeout = 5*(60*1000);
[Code]....
Also, if they click the Button that says, "I'm still here" to ping the server to keep them on the page working without logging them out, will that code cause a javascript error because now the tooltip popup window that has the timeCountDown will no longer be open, so how would them clicking the ping server button stop that from causing an error when it goes to update timeCountDown?

I'm new to javascript. I want to make multiple adjustable countdown timers on a single page. I've got a single timer working:
Code:
<script type="text/javascript">
var sec = 10; // set the seconds
var min = 00; // set the minutes
function countDown() {
sec--;
if (sec == -01) {

teaching myself javascript. my current self-challenge is to write a countdown clock that will tick off the days, hours, minutes, seconds until a certain date.i'm thinking that this should be what's happening in the javascript:
get current date/time (using new Date())
get future date/time counting down to (using new Date(2009,7,7))
subtract current from future (Math.ceil(movie.getTime - today.getTime))
convert resulting milliseconds to back to time format (not sure how to do that yet)write result back to html page (not sure how to do that yet, either)loop the whole thing every 1000 milliseconds.is this a workable idea? it seems the most straightforward way of doing it, but other scripts i've found on the web seem much more complicated.

I have a file system where users upload files. Using PHP the file is time stamped and that time stamp is saved in a database. This has been going on for months so I have a lot of files with server times saved in the database. Recently the client asked if the date/time could be displayed according to the client's timezone instead of the server's. So, I need a javascript function that will take a PHP formated date string and convert it to the clients time-zone.
So let's say there is a file with a date/time of 07/15/2004 1:15 PM in central time zone and the client is viewing the file today in pacific time zone (2 hrs diff.). I need to show that date/time as 07/15/2004 11:15 AM. I need JS to take གྷ/15/2004 1:15 PM' and somehow convert it to གྷ/15/2004 11:15 AM'. Code:

What is the best way to get the client time to the server? Would I user http headers? (I dont know how to do that) or is ajax the best method? I could use ajax to send the unix timestamp to the server everytime a page loads and save the difference between it and the server timestamp as a session variable. sounds sensible?
I dont want to work with timezones but I do want to get the actual time set on the client's computer.

I would like a counter/timer that will show in textboxes the time left to Saturday 07:00. When it reaches zero it should reset and calculate the time until the next Saturday 07:00, 4 weeks ahead...
Ex. next saturday is 19.3, when it resets it should set the timer to calculate the time to 16.4. 07:00, and when it resets again it should calculate the time to 14.4. 07:00. I hope you understand.

Trying to write a javascript countdown script. Here's what I got:
function timer(position,count)
{
var newCount
if (position == 'start') {
document.getElementById("timer").innerHTML=count
newCount = count - 1
alert(newCount);
setTimeout("timer('go',newCount)",1000)
}
if (position == 'go') {
document.getElementById("timer").innerHTML=count
} }
</script>
</head>
<body onload="timer('start',10);">
onload starts the timer at 10 and then my first step was to have to go down to 9. But I get this javascript error message: Error: newCount is not defined
But I have it as an alert right before I call it and it alerts the variable just fine. Why would it say it isnt defined?

I have a js countdown timer which counts down from 60 seconds to zero and when it hits zero it redirects the page.
Only problem is that when the user refreshes the page the timer obviously reverts to 60 seconds.
Does anyone have any code which would turn this into a cookie so that the location of the timer is stored each time the page is refreshed and then the timer continues from where it left off?
My timer is using setTimeout.
I've seen a couple of examples of this on various forums but none actually seem to work - my cookies are switched on.
Also, I cannot use form, input or anything else like this due to the third party software we're using.

I'm really struggling to write a bit of JS that displays the amount of time left to when your order will be shipped.For Example: If it's
1:05pm on Sunday, it would say: "Place your order within the next 1 day 2 hours 55 minutes and your order will ship Monday"
Another example: If it's 2:00pm on Saturday, it would say: "Place your order within the next 2 hours and your order will ship today"
I need to be able to change the cut off point from 4pm if needed...It must also ignore bank holiday (Ideally, it would have a section in the code where I could put all 'excluded' dates, e.g. 12/25/2009, 01/01/2010, etc. - This way I could keep it up to date).The code must take into account that we only deliver Monday to Friday (Therefore on a Friday after 4pm, it would not say delivery tomorrow, but Monday).Once the deadline hits (4pm), the countdown jumps back up to accommodate tomorrow's deadline, etc.Amazon does a very similar thing,

I'm trying to create a countdown timer based upon[URL]...what I'm trying to do: The database has a date, then there is a certain amount of seconds. Say 60*10 = 600 seconds / 10 minutes.
Everytime somebody buys something the datetime in database will be updated to the datetime item was bought. Now my goal is that anyone who is watching the timer in REAL time will have their timer reset to 10 minutes when somebody else buy.
Now the probem is this. The timer works sometimes only. Usually the first 3 times after a page load when somebody buys an item it works. Then it doesn't work. Or work at random intervals. It just doesn't make any sense to me!??

What I would like to do is watch a countdown timer on a page, like the ones on swoopo.co.uk and then perfom an action depending on what time is left on the timer.
I've installed DOM inspector on Firefox and poked around with javascript shell and I think I've figured out how to read the timer and assign that to a variable, something like this -
var timer=document.getElementById('counter_index_page_162980').innerHTML;
Now I need to watch that so I guessed this would do -
while (timer!=="00:00:01")
{
var timer=document.getElementById('counter_index_page_162980').innerHTML;
}
alert('timer at 1 sec!');
But that just brings up an "unresponsive script" error in my browser.
Am I even close to the mark? I know I'm not going to win any auctions with this but I've already paid for the bids so I may as well use them now.
