PHP parsing date with timezone from a string

I want to parse the date with the timezone from a string in the format "2021-12-10T18:49:00-05:00". I tried to parse using "date('Y-m-d h:i:s', strtotime($myDate))". But it is returning date of next day. Any help is much appreciated.

The parsing bit of your code is done by strtotime() and it works just fine. The problem is in your debugging code, which translates the parsed date to a different time zone. Please compare:

$date = strtotime('2021-12-10T18:49:00-05:00');

var_dump(date_default_timezone_get(), date('r', $date));

date_default_timezone_set('Asia/Tokyo');
var_dump(date('r', $date));

date_default_timezone_set('America/Los_Angeles');
var_dump(date('r', $date));

string(16) "Europe/Amsterdam"
string(31) "Sat, 11 Dec 2021 00:49:00 +0100"
string(31) "Sat, 11 Dec 2021 08:49:00 +0900"
string(31) "Fri, 10 Dec 2021 15:49:00 -0800"

The result of strtotime() is a Unix timestamp, which is a fixed moment in time and isn't linked to any specific time zone. If you don't want to lose the time zone information you can use DateTime objects:

$date = new DateTime('2021-12-10T18:49:00-05:00');
var_dump($date);

object(DateTime)#1 (3) {
  ["date"]=>
  string(26) "2021-12-10 18:49:00.000000"
  ["timezone_type"]=>
  int(1)
  ["timezone"]=>
  string(6) "-05:00"
}

This is something that only really matters if you application can actually handle different time zones.

The DateTime object can work well with time zones. The simple solution is therefore:

$strDate = "2021-12-10T18:49:00-05:00";
$dateTime = new DateTime($strDate);
var_dump($dateTime);
/*
object(DateTime)#2 (3) {
  ["date"]=>
  string(26) "2021-12-10 18:49:00.000000"
  ["timezone_type"]=>
  int(1)
  ["timezone"]=>
  string(6) "-05:00"
}
*/

The setTimeZone method can now be used to convert the date for any desired time zone.

$dateTime->setTimeZone(new DateTimeZone('UTC'));
echo $dateTime->format('Y-m-d H:i:s');
//2021-12-10 23:49:00

I get the local time with

$tz = date_default_timezone_get();
$dateTime->setTimeZone(new DateTimeZone($tz));
echo $dateTime->format('Y-m-d H:i:s');

The result depends on the local time zone. For "Europe/Berlin" I get the result

2021-12-11 00:49:00

I get the same result (2021-12-11 00:49:00) with date and strtotime.

short answer:

echo date('c'); //output 2021-12-10T17:28:24+03:00

to convert given date format use:

echo date('c', strtotime('2021-12-10')); //output 2021-12-10T00:00:00+03:00

Use DateTimeInterface::ATOM to format your date:

date(DateTimeInterface::ATOM, strtotime('now'));

This outputs 2021-12-10T14:23:37+00:00
