Calculate The Time Different?

May 9, 2010

I built 2 steps script - in the first page the visitor choose the date he want to schedual his appoitment and his location:

PHP Code:

<select name='zone'>
<option value='-4' selected> USA - EST</option>
<option value='-7'>USA - PST</option>

[code]....

In the second page he need to choose the time he want for his appointment (the time is in GMT+3 -> my local time). in this page the script also get the time zone and the date that he choose in the previous page (using POST - PHP). the date saved in variable. I used unix time (MKTIME function) I want that every time my visitor choose time (from drop-down box) a new cell/DIV will appear with his local time.for example - when he choose date: 10 May 2010, time zone: Austrlia - East Coast (+8 Hours) and time 22:00, New DIV will appear with the date "11 May 2010, 03:00AM" (there are 5 hours different).what is the JS what caculate and show the visitor local time?(I have, in PHP, only his time zone and the date that he coose in the first page)

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.

Calculate And Display TOTAL Time On Website?

Mar 25, 2009

I have a Javascript that calculates and displays how long, in minutes and seconds a user has been in online(Google Gears development) mode on a given web page. I need however, to modify the script so that it calculates and displays how long the user has been online on the web site. For e.g. on page 1 for 2 minutes 12 seconds. Moves to page 2 - total time on page 1 and 2= 4 minutes 13 seconds. My script (see below) starts a second counter then converts that to minutes and seconds. I have tried passing the secVar0 variable in the url but that comes back "undefined".

Code:

if(request.responseText != "" && request.responseText.indexOf("404 Page not found") == -1)
{
c=0;

Script With Document.write Inside Iframe Hangs First Time, Works Second Time (in IE)?

Dec 22, 2010

I have put together a script which does this:

1. Make ajax request (via getHTTPObject(), no libraries is used)

2. Create an iframe with script, src is "blank.html".

3. use iframe.document.write() to execute scripts (inkluding document.write based scripts) in the iframe.

4. call parent window's document to clone the iframe content.

5. Append the content clone to parent body.

Works like a charm in all browsers but IE, where every version - including IE9 beta - hangs on iframeWindow.document.close() with empty cache, leaving the window/tab unresponsible. When I force quit, restart and load the page again (now in cache) it works.What I've tried already:

* Googled.

* called the ajax request callback manually with string instead of request.responseText - it works even with empty cache here.Removed document.close() - resulting in scripts in iframe not executing at all (again, only with empty cache, cached pages works fine).

* Tested to make the ajax request synchronous - no difference.

Console.log trace:

Code:
append() begin
unlimited-scroll.js:160 install() begin
unlimited-scroll.js:194 iframe begin[code].....

Automating Text To Change Daily At Specific Time To Website Viewers Time?

Sep 17, 2011

I do pretty much all the computer related tasks, which includes computer system repair, audio/video editing, cd/dvd printing and duplication, document format and creation, etc etc. But when it comes to HTML (or other codes) I know very little. But we needed a website, so I use Homestead hosting and the Homestead (offline) Site Builder program.

Anyway, inside the sight builder program, they have the option to insert HTML Snippets. Which I use for various objects, off site tools, and other. But now I need to do something for which I have not been able to find a "premade" html code object, that can perform the task desired. I have searched and searched google and went through many sites, including this one. I have tried to take some codes which I thought I could alter to make it perform, but they just wouldn't work for what I needed them to do.

I need a code that will automate a "specific text message" to change daily, and to schedule a "different specific text message" to appear each day. I need to be able to schedule each days "texts" at the very least 31 days in advance. In other words, I need to make an array (I think that's what it is called) for the entire month:

Day 1 "today's text 1"
Day 2 "today's text 2"
Day 3 "today's text 3"

[code]....

If were possible to make an "array" that would go six months out (or more) that would be very helpful! But the longest that I have seen is one month at a time, so that may be as long as they go, but I'm not sure.On top of all of this, I need these changes to be performed at a specific time of the day. I would like them to be preformed at sunset everyday, but I don't think there is anyway to direct the code to look at like [URL] sunset times or such. So if I can at least choose a specific hour, like 8:00 pm, that will work, I will just have to adjust this every once in a while.

However, I don't want it to change just at 8:00pm in my timezone. I need it to change at 8:00pm according to the website viewers timezone. Is there a way to make the code "look" at the users computer and "get their time" and use that to adjust what text is displayed? In other words, I live in Indiana USA. If someone in Australia looked up the webpage on the 15th day of the month, but it was 9:00pm Their Time. The text I need to be displayed should be for "Day 16" from the array.

Populate Select Boxes - Create Events, With A Start Time And An End Time?

Jun 3, 2009

I'd like some direction on creating a small piece of Javascript that will populate my <select> boxes.Basically, I have a form for users to create events, with a start time and an end time. (These are the two select boxes).For example:

Code:
<select id="startTime">
<option value="12:00AM">12:00AM</option>
<option value="12:15AM">12:15AM</option>
etc.....
</select>

What I am trying to do is:

1) Have times populated in 15 minute incrementals from 12:00AM to 11:45PM

2) Have some type of "error checking" available to where the End Time must be after the start time. It would be nice for the script to automatically change the end time field to a time that is after the start time.

Live Clock With Date, Time, And Time Zone?

Jun 7, 2009

I have scoured the net and found nearly what I'm looking for, but not exactly, and I don't really know javascript, so trying to piece together bits of code hasn't worked. What I need is the script for a live clock with date and time format exactly as follows: Sunday, 07 June 2009, 24:00:00 (GMT+1).I have two separate files with the following code, which gets me close to what I need: Sun Jun 07 19:05:48 2009 Obviously the time is in the wrong place and it doesn't show GMT+1. These are the scripts:

Code:
function update() {
time = Date();[code]....

Convert Time String To Real Time Value

Mar 4, 2009

I need to convert a string containing the time to a real time value so I can insert it in to a time column in my database. tempElapsed = "1:22:33:44:555"

var _tempElapsedHours = tempElapsed.substring(2,4);
var _tempElapsedMinutes = tempElapsed.substring(5,7);
var _tempElapsedSeconds = tempElapsed.substring(8,10);
var _elapsed = Date.parse(new Date(_tempElapsedHours,_tempElapsedMinutes,_tempElapsedSeconds));

The result of elapsed is -1.4243e+012, I was hoping for a time value of 22:33:44

Time Zone Conversion Not Using Current Time

Mar 8, 2011

I'm not really a Java writer, so I don't know how to do this myself, though I imagine it would be pretty simple. I am looking to add a script to a webpage that allows users to input a time manually, and have it converted to GMT/Zulu time and display the converted time. I have seen a lot of time zone conversion scripts online, but they all just convert whatever the current system time is to another time zone. I am looking for a script that allows users to convert a time and show the zulu time, for times other than the current time. The time zone the inputed local time would be in is +4:30 (Kabul). I don't really care about style or aestehtics, just a simple script I can insert into a web page to have a time input field. The converted output time can appear in another field, a popup bubble, etc, again style isn't really an issue. It's really just to help people in my job who need to know what the GMT/Zulu time was for certain local times after the fact. One would think it shouldn't be that hard to just subtract 4:30 in your head, but apparently it is.

Convert UTC Time To A Definable Local Time?

Apr 15, 2010

There are probably a million threads about time conversion, but I cannot find the answer to my problem. So I'm making it a million and one...

I have my date/time stamps stored in UTC (ie number of second since the Unix Epoch). How do I convert this to a definable local time in JavaScript? With definable I mean any local time, not necessarily the machine local time.

In PHP I would do it as follows:

Code:
$utc = time(); // current UTC
$timezone = "America/New_York";
date_default_timezone_set($timezone);
echo date("Y-m-d H:i:s", $utc);

The above would give the current date/time in New York. I would like to be able to do this in JavaScript for any time given in UTC.
