PHP - Format Timestamp To Timezone

Code: [Select]
function time_ago($timestamp)
{
//$months = array("Jan" => 31, "Feb" => 28, "Mar" => 31, "Apr" => 30, "May" => 31, "Jun" => 30, "Jul" => 31, "Aug" => 31, "Sept" => 30, "Oct" => 31, "Nov" => 30, "Dec" => 31);
$curr_time = time();
$time_ago = $curr_time - $timestamp;
if($time_ago < 60) // seconds
{
$ext = $time_ago . " seconds ago..";
}
else
{
if($time_ago >= 60) // minutes
{
$time = floor($time_ago / 60);
$seconds_remainder = $time_ago % 60;
$ext = $time . " minutes " . $seconds_remainder . " seconds ago..";

if($time >= 60) // hours
{
$hours = floor($time / 60);
$minutes = $time % 60;
$ext = $hours . " hours " . $minutes . " minutes ago..";
if($hours >= 24) // days
{
$days = floor($hours / 24);
$day_hours = $hours % 24;
$ext = $days . " days " . $day_hours . " hours ago ..";
}
}
}
}
return $ext;
}

It seems to work fine (was going to tackle Months but haven't done it yet), but anyway is there a better way to do this? I'm guessing there is as I wrote this up rather fast and I'm not that great with date math. Any suggestions are appreciated (besides maybe using ternaries which I'm working on atm).

Hello All, 
  Need an advise in finishing this task please. 
 

function convertTimeFormat($time12Hour) {
// Initialized required variable to an empty string.
		$time24Hour = ""; 

// Used explode() function to break the string into an array and stored its value in $Split variable. 
		$Split = explode(":",$time12Hour); // print_r(explode (":", $time12Hour)); => Array ( [0] => 09 [1] => 50 [2] => 08AM )

// Retrieved only "hour" from the array and stored in $Hour variable. 
		$Hour = $Split[0];   

    $Split[2] = substr($Split[2],0,2);

// Used stripos() function to find the position of the first occurrence of a string inside another string.	
		if($Hour == '12' && strpos($time12Hour,"AM")!== FALSE) {
			// Code here 
		} elseif(strpos($time12Hour,"PM")!== FALSE && $Hour != "12") {
			// code here
		}
		return  $time24Hour;
	}
	$time12Hour = "09:50:08AM";
	$result = convertTimeFormat($time12Hour);
	print_r($result); 

/*
Input : "09:50:08AM";
Output : "21:50:08PM";

Hi all,

I am currently making a website that has e-custom functions and a back end for the client.

I want them to be able to upload images - but they need to be transparent. I do not want to leave this in the hands of the client, so I am looking at ways of using the GD library to make the change

I got no issue with the png/gif type for upload/resize function since this type already transparent background but my major problems is how to deal with jpeg/jpg image type which is their background was not a transparent...so is it possible I can change/ convert to png/gif type upon successful of uploading image...so the new final image will be png/gif type with transparent background...is it doable...I am not even sure it is possible...?

Thanks for any help..

Strict Standards: DateTime::__construct() [datetime.--construct]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Chicago' for 'CDT/-5.0/DST' instead in /home/elliottw/public_html/login/inc/conn.inc.php on line 45


And the code I am using is:
$timezone = new DateTimeZone("Europe/London");
$date = new DateTime();
$date->setTimezone($timezone);
$dateTime = $date->format('H:i:s d/m/Y'); 
$sqlDateTime = $date->format('Y-m-d H:i:s');

I've come to the end of my tether. I can't see anything wrong with this, searched Google and I'm starting to go crazy (partly due to the Caffeine and staring at code for 4 hours).

Any help would be greatly appreciated!
Cheers.

I just upgraded from 5.2.x to 5.3.3 this morning, and am now confronted with the "infamous"
Code: [Select]
It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the

 C:\Inetpub\wwwroot\ATSTest\sys\class\class.calendar.inc.php on line 98


Previously I just let php pull the system time to keep everything accurate with DST.  Now that I'm having to use the date.timezone setting in php.ini, how can I tell it to factor in DST, or do I now have to manually perform a calculation in my methods/functions to check and adjust?  Or does it automagically recognize the DST by setting it to Code: [Select]
date.timezone = America/New_York (yeah, right...what are the odds of *that*?

I am in need of a script that can detect a visitors timezone with out using geoip and with out the user providing the information. Any help on this or references would be greatly appreciated.

hey im writing a page that does the timezones for 5:00 around the world and i found this template the only thing is it didnt include the timezone.php file the js is loading this new Ajax('timezone.php?tz='+String(timezone),{onComplete:tzCLB, method: 'get'}).request();

what it does is retrieves a list of countries from that file i think. How and what would i need to do to make a timezone.php that would get the countries. Thanks

How would I change the current timezone used within a php script?

The method I usually use, date_default_timezone_set() is undefined on my webhost, so I am trying to find another way.

instead of js alert displaying the timezone offset, i would like the content of get_time_zone_offset() to be used as a php variable.

<script type="text/javascript">
    function get_time_zone_offset( ) {
        var current_date = new Date();
        return -current_date.getTimezoneOffset() / 60;
    }

    alert("The local time zone is: GMT " + get_time_zone_offset());
</script>

Hi, I am trying to get the date and time that a particular table was last updated, which the code below does, but it doesn't seem to be putting it in the correct timezone, it is 5 hours behind, anyone know why this is? or how i can fix it? Thanks

Code: [Select]
<?php
date_default_timezone_set('Europe/London');
        $query = "SELECT UPDATE_TIME FROM information_schema.tables WHERE TABLE_SCHEMA = 'tffdb' AND TABLE_NAME = 'test_team_points'";
        $result = mysql_query($query) or die(mysql_error());
        
        $row = mysql_fetch_assoc($result);
echo $row['UPDATE_TIME'];

?>

Developing apps is great until I have to start dealing with blasted timezones. For some reason this aspect of it always does my head in.

At the moment I'm storing all dates in the DB as GMT with the format Y-m-d H:i:s. I figure it's good to be consistent and store dates in GMT then convert to the users desired timezone. So I allow users to choose there timezone, based off the defined PHP timezones that can be used with the DateTimeZone class.

My problem, however, arises with the whole syncing of times. Let's say I post something right now. The date gets stored in in the database as: 2012-04-14 02:35:49
Now I'm in GMT +10 (possibly the greatest of timezones ), so I've set my timezone in my settings as Australia/Melbourne and when displaying date/times locally I do something like this:

Code: [Select]
public static function local($user, $date, $format = 'F j, Y, h:ia')
{
$date = new DateTime($date);

return $date->setTimezone(new DateTimeZone($user->timezone))->format($format);
}
So running the stored date above through my method gives me a date like this: April 14, 2012, 12:35pm

Awesome.

My question is: I noticed that on say, Twitter, when you change your timezone your tweet dates don't change. They remain as the date/time of my actual timezone, regardless of what I set it too. With my implementation however, if I change my timezone to GMT +12 (Fiji) my post is now posted at: April 14, 2012, 02:35pm

So is what I'm doing right? My head has about had it.

Thanks.

Hi all

I've got an issue with time zones for displaying information.  I'm hoping someone might know of a guide that would cover the following.  I'm struggling to find one!  Basically I have many online events to list in many different timezones.  Users may wish to use their time zone to display information in.  What I would like to do is store a timestamp and timezone for each event, then will need (I think!) to convert all to a single timezone in order to list them chronologically.  From that I would then convert them into the user's desired timezone and display to the page.

The idea to is avoid changes in time throughout the year, so it does it all automatically.

Any links, tips, words of advice very gratefully received!

Hi,   Please help to resolve this script.   Default time zone is not working properly it shows time only in AM (PM is not working) and in the INDIAN time 7:00pm  to 7:00am table never fetch any content.
