So I've checked the list of supported time zones in PHP and I was wondering how could I include them in the date() function?
Thanks!
I don't want a default timezone, each user has their timezone stored in the database, I take that timezone of the user and use it. How? I know how to take it from the database, not how to use it, though.
For such task, you should really be using PHP's DateTime class. Please ignore all of the answers advising you to use date() or date_set_time_zone, it's simply bad and outdated.
I'll use pseudocode to demonstrate, so try to adjust the code to suit your needs.
Assuming that variable $tz contains string name of a valid time zone and variable $timestamp contains the timestamp you wish to format according to time zone, the code would look like this:
$tz = 'Europe/London';
$timestamp = time();
$dt = new DateTime("now", new DateTimeZone($tz)); //first argument "must" be a string
$dt->setTimestamp($timestamp); //adjust the object to correct timestamp
echo $dt->format('d.m.Y, H:i:s');
DateTime class is powerful, and to grasp all of its capabilities - you should devote some of your time reading about it at php.net. To answer your question fully - yes, you can adjust the time zone parameter dynamically (on each iteration while reading from db, you can create a new DateTimeZone() object).
If I understood correct,You need to set time zone first like:
date_default_timezone_set('UTC');
And than you can use date function:
// Prints something like: Monday 8th of August 2005 03:12:46 PM
echo date('l jS \of F Y h:i:s A');
The answer above caused me to jump through some hoops/gotchas, so just posting the cleaner code that worked for me:
$dt = new DateTime();
$dt->setTimezone(new DateTimeZone('America/New_York'));
$dt->setTimestamp(123456789);
echo $dt->format('F j, Y # G:i');
Use the DateTime class instead, as it supports timezones. The DateTime equivalent of date() is DateTime::format.
An extremely helpful wrapper for DateTime is Carbon - definitely give it a look.
You'll want to store in the database as UTC and convert on the application level.
It should like this:
date_default_timezone_set('America/New_York');
U can just add, timezone difference to unix timestamp.
Example for Moscow (UTC+3)
echo date('d.m.Y H:i:s', time() + 3 * 60 * 60);
Try this. You can pass either unix timestamp, or datetime string
public static function convertToTimezone($timestamp, $fromTimezone, $toTimezone, $format='Y-m-d H:i:s')
{
$datetime = is_numeric($timestamp) ?
DateTime::createFromFormat ('U' , $timestamp, new DateTimeZone($fromTimezone)) :
new DateTime($timestamp, new DateTimeZone($fromTimezone));
$datetime->setTimezone(new DateTimeZone($toTimezone));
return $datetime->format($format);
}
this works perfectly in 2019:
date('Y-m-d H:i:s',strtotime($date. ' '.$timezone));
I have created this very straightforward function, and it works like a charm:
function ts2time($timestamp,$timezone){ /* input: 1518404518,America/Los_Angeles */
$date = new DateTime(date("d F Y H:i:s",$timestamp));
$date->setTimezone(new DateTimeZone($timezone));
$rt=$date->format('M d, Y h:i:s a'); /* output: Feb 11, 2018 7:01:58 pm */
return $rt;
}
I have tried the answers based on the DateTime class. While they are working, I found a much simpler solution that makes a DateTime object timezone aware at the time of creation.
$dt = new DateTime("now", new DateTimeZone('Asia/Jakarta'));
echo $dt->format("Y-m-d H:i:s");
This returns the current local time in Jakarta, Indonesia.
Not mentioned above. You could also crate a DateTime object by providing a timestamp as string in the constructor with a leading # sign.
$dt = new DateTime('#123456789');
$dt->setTimezone(new DateTimeZone('America/New_York'));
echo $dt->format('F j, Y - G:i');
See the documentation about compound formats:
https://www.php.net/manual/en/datetime.formats.compound.php
Based on other answers I built a one-liner, where I suppose you need current date time. It's easy to adjust if you need a different timestamp.
$dt = (new DateTime("now", new DateTimeZone('Europe/Rome')))->format('d-m-Y_His');
If you use Team EJ's answer, using T in the format string for DateTime will display a three-letter abbreviation, but you can get the long name of the timezone like this:
$date = new DateTime('2/3/2022 02:11:17');
$date->setTimezone(new DateTimeZone('America/Chicago'));
echo "\n" . $date->format('Y-m-d h:i:s T');
/* Displays 2022-02-03 02:11:17 CST "; */
$t = $date->getTimezone();
echo "\nTimezone: " . $t->getName();
/* Displays Timezone: America/Chicago */
$now = new DateTime();
$now->format('d-m-Y H:i:s T')
Will output:
29-12-2021 12:38:15 UTC
I had a weird problem on a hosting. The timezone was set correctly, when I checked it with the following code.
echo ini_get('date.timezone');
However, the time it returned was UTC.
The solution was using the following code since the timezone was set correctly in the PHP configuration.
date_default_timezone_set(ini_get('date.timezone'));
You can replace database value in date_default_timezone_set function,
date_default_timezone_set(SOME_PHP_VARIABLE);
but just needs to take care of exact values relevant to the timezones.
I have a UTC timestamp value 1615958170523 and I want to convert it into our local timezone.
I have tried this method:
The timestamp is in milliseconds that's why firstly I have converted in seconds and then used the below method.
$Date = date('m-d-Y H:i:s', 1615958170523/1000);
It always returns the time ~6hours ago i.e 03-17-2021 05:16:10 (Considering current time here), I don't want to add +5:30 hours to do the same.
Is it possible that we can use a standard method that means in-built functions which may be provided by Cakephp or PHP so that I can get the answer for the same?
I have also tried this one:
$gmtTimezone = new \DateTimeZone('GMT');
$myDateTime = new \DateTime(1615958170523/1000, $gmtTimezone);
It returns the same as I have used the date function.
You need to change the timezone after to define the timestamp in GMT.
$timestamp = 1615958170523/1000;
$myDateTime = \DateTime::createFromFormat('U', (int)$timestamp);
echo $myDateTime->format('Y-m-d H:i:s'), PHP_EOL; // 2021-03-17 05:16:10
$myDateTime->setTimezone(new \DateTimeZone('Europe/Paris'));
echo $myDateTime->format('Y-m-d H:i:s'), PHP_EOL; // 2021-03-17 06:16:10
$myDateTime->setTimezone(new \DateTimeZone('America/Denver'));
echo $myDateTime->format('Y-m-d H:i:s'), PHP_EOL; // 2021-03-16 23:16:10
See DateTime::setTimezone() documentation
You should use the FrozenTime which will use the default Timezone you set in your config/app.php
I am saving my timestamp in Laravel using the following.
Carbon::now()->timestamp;
How do you convert a timestamp into a specific time format with a specific timezone (using Carbon)?
$unix_time_stamp = "1572095520";
$date = Carbon::createFromTimestamp($unix_time_stamp);
$date->setTimezone('Pacific/Auckland')->format('Y-m-d H:i:s');
I am getting incorrect result on this one, should be Oct 27
Please try the following.
$unix_time_stamp = '1572095520';
$converted = Carbon::createFromTimestamp($unix_time_stamp,'Pacific/Auckland')
->toDateTimeString();
Go to config -> app.php and change 'timezone' => 'Pacific/Auckland',
I want to get a real timestamp of given time in specified timezone for using in frontend.
Currently i can set a timezone, and get the time for it. But i can't get a new one timestamp.
Carbon::setToStringFormat('U'); // Set __toString format
$instance = Carbon::createFromTimestamp('1460014482', "Europe/Kiev"); // Set global server timezone (or pickup from default PHP setting)
$instance->setTimezone("Indian/Maldives"); // Set user timezone
var_dump($instance->format('d M Y H:i:s')); // Shows the correct time +2 hours from Europe/Kiev
var_dump((string)$instance); // Shows the same timestamp specified in createFromTimestamp
var_dump(date('d M Y H:i:s', (string)$instance)) // So it won't show the timezone datetime
Explain how i can get a timestamp of time for a given timezone.
Thanks!
You need to use the function createFromFormat to use setTimezone. Here is an example for your code:
$originalDate = date("Y-m-d H:i:s", '1460014482');
$instance = Carbon::createFromFormat('Y-m-d H:i:s', $originalDate, 'Europe/Kiev');
$instance->setTimezone("Indian/Maldives");
Hope it helps.
I know its not a complete solution. But it works for my requirements.
Currently need to override __toString method of Carbon class, which i use to display date timestamp.
public function __toString()
{
return static::$toStringFormat == 'U' ? (string)strtotime($this->format('Y-m-d H:i:s')) : $this->format(static::$toStringFormat);
}
I want to convert 1373892900000 to Monday 2013/07/15 8:55 AM in Codeigniter.
However, I keep receiving a totally different result by converting the timestamp using the function i have written, please note:I need to change the dates according to different timezones, that is why I want to write it this way:
public function time_convert($timestamp){
$this->load->helper('date');
date_default_timezone_set('UTC');
$daylight_saving = TRUE;
$timezone = "UM4"; //toronto or new york timezone
$time = gmt_to_local($timestamp, $timezone, $daylight_saving);
$final_time = standard_date('DATE_RFC822', $time);
return $final_time;
}
Result from the above function is: Sat, 08 Dec 06 01:40:00 +0000
And if I don't put date_default_timezone_set('UTC'); in the above function, I get this date instead Sat, 08 Dec 06 02:40:00 +0100. My codeigniter seems to default the timezone to Europe/Berlin.
Can anyone please help me correct any of the mistakes I might have made?
Why not just use PHP's date function?
public function time_convert($timestamp){
return date('l Y/m/d H:i', $timestamp);
}
For different timezones use a DateTime object:
public function time_convert($timestamp, $timezone = 'UTC'){
$datetime = new DateTime($timestamp, new DateTimeZone($timezone));
return $datetime->format('l Y/m/d H:i');
}
Think that should work. Note: I tihnk you need at least PHP version 5.20 for the TimeZone class.
<?php
$time_str=1373892900000;
echo gmdate("fill with your format", $time_str);
?>
your format = format your time in php, reading this page for details.
http://php.net/manual/en/function.date.php
http://php.net/manual/en/function.gmdate.php
Appears as though an invocation of standard_date with the DATE_ATOM format may sort you:
echo unix_to_human(time(), true, 'us'); # returns 2013-07-12 08:01:02 AM, for example
There are a whole host of other options for the format, enumerated on the linked page.
This how to covert timestamp to date very simple:
echo date('m/d/Y', 1299446702);
to convert timestamp to human readable format try this:
function unix_timestamp_to_human ($timestamp = "", $format = 'D d M Y - H:i:s')
{
if (empty($timestamp) || ! is_numeric($timestamp)) $timestamp = time();
return ($timestamp) ? date($format, $timestamp) : date($format, $timestamp);
}
$unix_time = "1251208071";
echo unix_timestamp_to_human($unix_time); //Return: Tue 25 Aug 2009 - 14:47:51
if you want to convert it to a format like this: 2008-07-17T09:24:17Z than use this method
<?php
$timestamp=1333699439;
echo gmdate("Y-m-d\TH:i:s\Z", $timestamp);
?>

Your timestamp is coming from javascript on the client, I would guess, because it appears to be in milliseconds. php timestamps are in seconds. So to get the answer you want, first divide by 1000.
Showing the full year would have made the issue more obvious, as you would have seen the year as 45,506.
