Örnek 2 Intricacies of DateTimeImmutable::__construct()

<?php
date_default_timezone_set('America/Jamaica');

// Specified date/time in PHP's default time zone.
$date = new DateTimeImmutable('2000-01-01');
echo $date->format('Y-m-d H:i:sP') . "\n";

// Specified date/time in the specified time zone.
$date = new DateTimeImmutable('2000-01-01', new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "\n";

// Current date/time in your PHP's default time zone.
$date = new DateTimeImmutable();
echo $date->format('Y-m-d H:i:sP') . "\n";

// Current date/time in the specified time zone.
$date = new DateTimeImmutable('now', new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "\n";

// Using a UNIX timestamp.  Notice the result is in the UTC time zone.
$date = new DateTimeImmutable('@946684800');
echo $date->format('Y-m-d H:i:sP') . "\n";

// Non-existent values roll over.
$date = new DateTimeImmutable('2000-02-30');
echo $date->format('Y-m-d H:i:sP') . "\n";

Yukarıdaki örnek şuna benzer bir çıktı üretir:

2000-01-01 00:00:00-05:00
2000-01-01 00:00:00+12:00
2010-04-24 10:24:16-04:00
2010-04-25 02:24:16+12:00
2000-01-01 00:00:00+00:00
2000-03-01 00:00:00-05:00

Bilginize:

Rolled over dates can be detected by checking for warnings using DateTimeImmutable::getLastErrors().

Örnek 3 Changing the associated timezone

<?php
$timeZone = new \DateTimeZone('Asia/Tokyo');

$time = new \DateTimeImmutable();
$time = $time->setTimezone($timeZone);

echo $time->format('Y/m/d H:i:s e'), "\n";

Yukarıdaki örnek şuna benzer bir çıktı üretir:

2022/08/12 23:49:23 Asia/Tokyo

Örnek 4 Using a relative date/time string

<?php
$time = new \DateTimeImmutable("-1 year");

echo $time->format('Y/m/d H:i:s'), "\n";

Yukarıdaki örnek şuna benzer bir çıktı üretir:

2021/08/12 15:43:51

"If $timezone is omitted or null, the current timezone will be used." - note, that timezone IS NOT equal offset, if its important for your application.

If default timezone = Europe/Moscow, then:
echo (new \DateTimeImmutable('2014-10'))->format(DATE_ATOM); // gives "2014-10-01T00:00:00+04:00"
echo (new \DateTimeImmutable('2014-11'))->format(DATE_ATOM); // gives "2014-11-01T00:00:00+03:00"
because of law changes (abolition of "summer time").
