Returns new DateTime object.

Parameters

datetime

A date/time string. Valid formats are explained in Date and Time Formats.

Enter "now" here to obtain the current time when using the $timezone parameter.

timezone

A DateTimeZone object representing the timezone of $datetime.

If $timezone is omitted, the current timezone will be used.

Note:

The $timezone parameter and the current timezone are ignored when the $datetime parameter either is a UNIX timestamp (e.g. @946684800) or specifies a timezone (e.g. 2010-01-28T15:00:00+02:00).

Examples

Example #1 DateTime::__construct() example

Object oriented style

<?phptry { $date = new DateTime('2000-01-01');} catch (Exception $e) { echo $e->getMessage(); exit(1);}echo $date->format('Y-m-d');?>

Procedural style

<?php$date = date_create('2000-01-01');if (!$date) { $e = date_get_last_errors(); foreach ($e['errors'] as $error) { echo "$error\n"; } exit(1);}echo date_format($date, 'Y-m-d');?>

The above examples will output:

2000-01-01

Example #2 Intricacies of DateTime::__construct()

<?php// Specified date/time in your computer's time zone.$date = new DateTime('2000-01-01');echo $date->format('Y-m-d H:i:sP') . "\n";// Specified date/time in the specified time zone.$date = new DateTime('2000-01-01', new DateTimeZone('Pacific/Nauru'));echo $date->format('Y-m-d H:i:sP') . "\n";// Current date/time in your computer's time zone.$date = new DateTime();echo $date->format('Y-m-d H:i:sP') . "\n";// Current date/time in the specified time zone.$date = new DateTime(null, 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 DateTime('@946684800');echo $date->format('Y-m-d H:i:sP') . "\n";// Non-existent values roll over.$date = new DateTime('2000-02-30');echo $date->format('Y-m-d H:i:sP') . "\n";?>

The above example will output something similar to:

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
