I create a DateTime object like this
$timestamp = new DateTime('2018-04-23T07:01:05.146000+00:00');
$timestampSql = $messageTimestamp->format('Y-m-d H:i:s');
I then insert the $timestampSql into a timestamp field in my mysql table. But the problem is, that the mysql thinks that this time and date is in whatever timezone the mysql server is, and doesn't realize, that it is in fact originating from an ISO time.
So basically, I need to somehow make sure the ->format outputs the timestamp converted to the current timezone the server is set to.
Here is a way you can easily switch a timezone using the dateTime Object:
function convertDate($dateTime){
$utc = 'UTC';
$newTimZone = 'TimeZone';
$newDateTime = new DateTime($dateTime, new DateTimeZone($utc));
$newDateTime->setTimezone(new DateTimeZone($newTimZone));
return $newDateTime->format('Y-m-d H:i:s');
}
Please check below function for server and user time zone
$time_diff = get_timezone_offset('America/New_York');
if(! function_exists('get_timezone_offset'))
{
/*get time differ user and server */
function get_timezone_offset($remote_tz, $origin_tz = null) {
if($origin_tz === null) {
if(!is_string($origin_tz = date_default_timezone_get())) {
return false; // A UTC timestamp was returned -- bail out!
}
}
$origin_dtz = new DateTimeZone($origin_tz);
$remote_dtz = new DateTimeZone($remote_tz);
$origin_dt = new DateTime("now", $origin_dtz);
$remote_dt = new DateTime("now", $remote_dtz);
$offset = $origin_dtz->getOffset($origin_dt) - $remote_dtz->getOffset($remote_dt);
$offset = $offset/60;
return $offset;
}
}
$current_date = date("Y-m-d h:i:sa");
$new_date = $this->time_differction($current_date,$time_diff);
if(! function_exists('time_differction'))
{
/*Return new date and time as per user time zone */
function time_differction($date_time, $time_diff){
$time = strtotime($date_time);
$time = $time - ($time_diff * 60 );
$date = date("Y-m-d H:i:s", $time);
return $date;
}
}

Am trying to create a date and time function to check if a given dateTime and timezone passed but my function is always returning true even when i put a future date.
I have below example class
<?php
class JobTimer{
public function __construct() {
}
public function isDateTime($startOn, $timezone = "GMT"){
$nowTime = new \DateTime("NOW", new \DateTimeZone($timezone));
$startTime = \DateTime::createFromFormat('M d, Y H:i:s', $startOn, new \DateTimeZone($timezone));
return ($nowTime >= $startTime ? true : false);
}
}
?>
Usage
Everything is returning true, my expectation is to return false if current time based on timezone has not yet elapse or return true when time has elapse or time is now
<?php
$job = new JobTimer();
//if($job->isDateTime("2019-05-02 12:00AM", "Asia/Kuala_Lumpur")){
//if($job->isDateTime("2021-05-02 12:00AM", "Asia/Kuala_Lumpur")){
if($job->isDateTime("2020-05-02 12:00AM", "Asia/Kuala_Lumpur")){
echo "YES";
}else{
echo "NO";
}
?>
In your JobTimer class $startTime is false because your format for DateTime::createFromFormat() does not match the format of the date you are passing in as a parameter and causing it to fail.
M d, Y H:i:s matches May 02, 2020 12:00:00 which is not what you are passing to that class.
You should be using:
$startTime = \DateTime::createFromFormat('Y-m-d H:iA', $startOn, new \DateTimeZone($timezone));
Working code:
class JobTimer{
public function __construct() {
}
public function isDateTime($startOn, $timezone = "GMT"){
$nowTime = new \DateTime("NOW", new \DateTimeZone($timezone));
$startTime = \DateTime::createFromFormat('Y-m-d H:iA', $startOn, new \DateTimeZone($timezone));
return $nowTime >= $startTime;
}
}
$job = new JobTimer();
if($job->isDateTime("2020-05-02 12:00AM", "Asia/Kuala_Lumpur")){
echo "YES";
}else{
echo "NO";
}
Output:
NO
Demo
Change your function to this:
public function isDateTime($startOn, $timezone = "GMT"){
$nowTime = new \DateTime("NOW", new \DateTimeZone($timezone));
$startTime = new \DateTime($startOn, new \DateTimeZone($timezone));
return ($nowTime >= $startTime ? true : false);
}
Your argument passed to createFromFormat is wrong, and therefore not creating a DateTime correctly. You can just pass your $startOn and a DateTimeZone to create a instance of DateTime
There istimestamp field (not null) in UTC in database with value: 2019-08-09 20:06:08.
I tried to convert this time to local time using function:
private function toLocalTime($dateInUTC) {
$time = strtotime($dateInUTC.' UTC');
return date("d/m/Y H:i", $time);
}
Converting is:
$response = []; // Data is present here
foreach($response as $v) {
$v->created_at = $this->toLocalTime($v->created_at);
}
On line where I call $this->toLocalTime() I get exception:
I have tried this code:
$timestamp = '2019-08-09 10:41:00';
$date = Carbon::createFromFormat('Y-m-d H:i:s', $timestamp, 'UTC');
$date->setTimezone('your/timezone'); //
$new_date = $date->format('your new format'); // Y-m-d H:i:s
Maybe my $timestamp is empty somewhere?
As I can see you have Carbon in your project:
$timestamp = '2019-08-09 10:41:00';
$date = Carbon::createFromFormat('Y-m-d H:i:s', $timestamp, 'UTC');
$date->setTimezone('America/Argentina/Buenos_Aires'); // or your timezone
$new_date = $date->format('Y-m-d H:i:s'); // or your new format
in your example:
private function toLocalTime($dateInUTC)
{
// parse your date with carbon and set that as UTC
$date = Carbon::createFromFormat('Y-m-d H:i:s', $dateInUTC, 'UTC');
// set your timezone to get a local time.
$date->setTimezone('America/Argentina/Buenos_Aires'); // or your timezone
return = $date->format('Y-m-d H:i:s'); // or your new format
}
https://www.php.net/manual/en/timezones.php
If you don't have Carbon installed as your example using native php:
private function toLocalTime($dateInUTC)
{
$utc_date = \DateTime::createFromFormat('Y-m-d H:i:s', $dateInUTC), new DateTimeZone('UTC'));
$utc_date->setTimeZone(new \DateTimeZone('America/Argentina/Buenos_Aires'); // or your timezone
return $utc_date->format('Y-m-d H:i:s'); // or your new format
}
I have datetime 2017-10-11 09:40:42 of Asia/Karachi I want to convert it to unix timestamp.
Note: I have multiple records with different timezone eg: Australia/Sydney
I am failed to convert it from following code
function unixTimefromTime($thetime='now',$timezone){
if(is_numeric($thetime)){
$dt = new \DateTime('#'.$thetime);
$dt->setTimeZone(new \DateTimeZone($timezone));
return $dt->getTimestamp();
} else {
$date = new \DateTime($thetime, new \DateTimeZone($timezone));
return $date->getTimestamp();
}
}
unixTimefromTime('2017-10-11 09:40:42','Asia/Karachi');
function DateTimeToUnixFromTimezone($dateNTime,$timezone){
$date = new DateTime($dateNTime, new DateTimeZone($timezone));
return $date->getTimestamp() + $date->getOffset();
}
How do I convert a date/time string (e.g. 2011-01-01 15:00:00) that is UTC to any given timezone php supports, such as America/New_York, or Europe/San_Marino.
PHP's DateTime object is pretty flexible.
$UTC = new DateTimeZone("UTC");
$newTZ = new DateTimeZone("America/New_York");
$date = new DateTime( "2011-01-01 15:00:00", $UTC );
$date->setTimezone( $newTZ );
echo $date->format('Y-m-d H:i:s');
PHP's DateTime object is pretty flexible.
Since the user asked for more than one timezone option, then you can make it generic.
Generic Function
function convertDateFromTimezone($date,$timezone,$timezone_to,$format){
$date = new DateTime($date,new DateTimeZone($timezone));
$date->setTimezone( new DateTimeZone($timezone_to) );
return $date->format($format);
}
Usage:
echo convertDateFromTimezone('2011-04-21 13:14','UTC','America/New_York','Y-m-d H:i:s');
Output:
2011-04-21 09:14:00
Assuming the UTC is not included in the string then:
date_default_timezone_set('America/New_York');
$datestring = '2011-01-01 15:00:00'; //Pulled in from somewhere
$date = date('Y-m-d H:i:s T',strtotime($datestring . ' UTC'));
echo $date; //Should get '2011-01-01 10:00:00 EST' or something like that
Or you could use the DateTime object.
function _settimezone($time,$defaultzone,$newzone)
{
$date = new DateTime($time, new DateTimeZone($defaultzone));
$date->setTimezone(new DateTimeZone($newzone));
$result=$date->format('Y-m-d H:i:s');
return $result;
}
$defaultzone="UTC";
$newzone="America/New_York";
$time="2011-01-01 15:00:00";
$newtime=_settimezone($time,$defaultzone,$newzone);
General purpose normalisation function to format any timestamp from any timezone to other.
Very useful for storing datetimestamps of users from different timezones in a relational database. For database comparisons store timestamp as UTC and use with gmdate('Y-m-d H:i:s')
/**
* Convert Datetime from any given olsonzone to other.
* #return datetime in user specified format
*/
function datetimeconv($datetime, $from, $to)
{
try {
if ($from['localeFormat'] != 'Y-m-d H:i:s') {
$datetime = DateTime::createFromFormat($from['localeFormat'], $datetime)->format('Y-m-d H:i:s');
}
$datetime = new DateTime($datetime, new DateTimeZone($from['olsonZone']));
$datetime->setTimeZone(new DateTimeZone($to['olsonZone']));
return $datetime->format($to['localeFormat']);
} catch (\Exception $e) {
return null;
}
}
Usage:
$from = ['localeFormat' => "d/m/Y H:i A", 'olsonZone' => 'Asia/Calcutta'];
$to = ['localeFormat' => "Y-m-d H:i:s", 'olsonZone' => 'UTC'];
datetimeconv("14/05/1986 10:45 PM", $from, $to); // returns "1986-05-14 17:15:00"
How about:
$timezone = new DateTimeZone('UTC');
$date = new DateTime('2011-04-21 13:14', $timezone);
echo $date->format;
Basically what I need is an script that, when provided with a time and a timezone can return the time in another time zone.
My main issues are:
Where to get the time offset from GMT from - is there a public database available for this?
How to also take into consideration the daylight saving time (DST) differences as well.
How to nicely wrap it all up inside an PHP class - or is there such a class already available?
<?php
$date = new DateTime('2000-01-01', new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "\n";
$date->setTimezone(new DateTimeZone('Pacific/Chatham'));
echo $date->format('Y-m-d H:i:sP') . "\n";
?>
The above examples will output:
2000-01-01 00:00:00+12:00
2000-01-01 01:45:00+13:45
found on DateTime Manual on php.net
EDIT:
Like Pekka said: The DateTime class exists from 5.2 on and there you first have to find out which of the methods are realy implemented and which one only exist from 5.3 on.
try this, it might help :)
function converToTz($time="",$toTz='',$fromTz='')
{
// timezone by php friendly values
$date = new DateTime($time, new DateTimeZone($fromTz));
$date->setTimezone(new DateTimeZone($toTz));
$time= $date->format('Y-m-d H:i:s');
return $time;
}
A bit description:
The function takes 3 inputs, time to convert, timezone to convert to, current timezone and returns the output in the specified format.
I know its late. For anyone who would want simple function to convert utc to any local time zone
function UTCTimeToLocalTime($time, $tz = '', $FromDateFormat = 'Y-m-d H:i:s', $ToDateFormat = 'Y-m-d H:i:s')
{
if ($tz == '')
$tz = date_default_timezone_get();
$utc_datetime = DateTime::createFromFormat($FromDateFormat, $time, new
DateTimeZone('UTC'));
$local_datetime = $utc_datetime;
$local_datetime->setTimeZone(new DateTimeZone($tz));
return $local_datetime->format($ToDateFormat);
}
echo UTCTimeToLocalTime('2015-07-01 13:30:00','America/Denver');
To convert from the given timezone to the desired timezone, we just have to add/subtract the difference of timezones (in SECONDS) to given timezone.
$my_timestamp = strtotime("2020-09-22 14:07:26");
/*
Convert timezones difference into seconds
from -7:00 to +5:30 have 12hrs and 30min difference
So in seconds, 12.5*60*60 is equaled to 45000 seconds
*/
$time_zone_difference = 45000;
//Use date function to get datetime in your desired formate
echo date("Y-m-d h:i:sa", $my_timestamp + time_zone_difference );
or we can write it like
Below given functions are for additional help.
Convert timezone differences in seconds, (which you can hardcode, if it is fixed throught the project):
function timezoneDifferenceInSec( $source_timezone, $required_timezone){
$a = explode(":",$source_timezone);
$b = explode(":",$required_timezone);
$c = (intval($a[0])*60+intval($a[1]))*60;
$d = (intval($b[0])*60+intval($b[1]))*60;
$diffsec =0;
if($c < $d)
$diffsec = $d-$c;
else
$diffsec = $c-$d;
return $diffsec;
}
//function call
$differenc = timezoneDifferenceInSec("-07:00", "+05:30");
Function to convert DateTime into required Timezone (if difference is known):
//datetime in String and timezone_differe is in int
function convertTimezone( $source_date_time, $timezone_diff_in_sec){
return date("Y-m-d h:i:sa", strtotime($source_date_time) + $timezone_diff_in_sec);
}
//function call
$timestamp = "2020-09-22 14:07:26";
$timezone_difference = 4500; //ie from -07:00 to +05:30
echo convertTimezone( $timestamp, $timezone_difference);
Function to convert DateTime into required Timezone (if difference in seconds among the timezones is known):
example: Timestamp give is "2020-09-22 14:07:26".
Timezones difference in seconds id 4500; //ie from -07:00 to +05:30
// timestamp as in String and timezones_diff_in_sec is in int
function convertTimezone( $timestamp, $timezones_diff_in_sec){
return date("Y-m-d h:i:sa", strtotime($source_date_time) + $timezones_diff_in_sec);
}
Function call (
//function call
$timestamp = "2020-09-22 14:07:26";
$timezone_difference = 4500; //ie from -07:00 to +05:30
echo convertTimezone( $timestamp, $timezone_difference);
Here i use this function for converting datetime into another timezone.
For best result if you convert your datetime into utc timezone and then convert into required timezone then it is better result for it.
function ConvertTimezoneToAnotherTimezone($time, $currentTimezone, $timezoneRequired) {
$dayLightFlag = false;
$dayLgtSecCurrent = $dayLgtSecReq = 0;
$system_timezone = date_default_timezone_get();
$local_timezone = $currentTimezone;
date_default_timezone_set($local_timezone);
$local = date("Y-m-d H:i:s");
/* Uncomment if daylight is required */
// $daylight_flag = date("I", strtotime($time));
// if ($daylight_flag == 1) {
// $dayLightFlag = true;
// $dayLgtSecCurrent = -3600;
// }
date_default_timezone_set("GMT");
$gmt = date("Y-m-d H:i:s ");
$require_timezone = $timezoneRequired;
date_default_timezone_set($require_timezone);
$required = date("Y-m-d H:i:s ");
/* Uncomment if daylight is required */
// $daylight_flag = date("I", strtotime($time));
// if ($daylight_flag == 1) {
// $dayLightFlag = true;
// $dayLgtSecReq = +3600;
// }
date_default_timezone_set($system_timezone);
$diff1 = (strtotime($gmt) - strtotime($local));
$diff2 = (strtotime($required) - strtotime($gmt));
$date = new DateTime($time);
$date->modify("+$diff1 seconds");
$date->modify("+$diff2 seconds");
if ($dayLightFlag) {
$final_diff = $dayLgtSecCurrent + $dayLgtSecReq;
$date->modify("$final_diff seconds");
}
$timestamp = $date->format("Y-m-d H:i:s ");
return $timestamp;
}
Thank You.
