Description

Object-oriented style

public DateTime DateTime::setTimezone(DateTimeZone $timezone)

Procedural style

DateTime date_timezone_set(DateTime $object, DateTimeZone $timezone)

Sets a new timezone for a DateTime object.

Like DateTimeImmutable::setTimezone but works with DateTime.

The procedural version takes the DateTime object as its first argument.

Parameters

Procedural style only: A DateTime object returned by date_create. The function modifies this object.

timezone

A DateTimeZone object representing the desired time zone.

Return Values

Returns the DateTime object for method chaining. The underlaying point-in-time is not changed when calling this method.

Examples

Example #1 DateTime::setTimeZone example

Object-oriented style

<?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 example will output:

2000-01-01 00:00:00+12:00
2000-01-01 01:45:00+13:45

Procedural style

<?php
$date = date_create('2000-01-01', timezone_open('Pacific/Nauru'));
echo date_format($date, 'Y-m-d H:i:sP') . "\n";

date_timezone_set($date, timezone_open('Pacific/Chatham'));
echo date_format($date, 'Y-m-d H:i:sP') . "\n";

The above example will output:

2000-01-01 00:00:00+12:00
2000-01-01 01:45:00+13:45
