DateTime::__construct -- date_create — Returns new DateTime object

### Description

Object oriented style

public DateTime::__construct ([ string `$time` = "now" [, DateTimeZone `$timezone` = `NULL` ]] )

Procedural style

DateTime date_create ([ string `$time` = "now" [, DateTimeZone `$timezone` = `NULL` ]] )

Returns new DateTime object.

### Parameters

`time`

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

  Enter `NULL` here to obtain the current time when using the `$timezone` parameter.

`timezone`

  A DateTimeZone object representing the timezone of `$time`.

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

  > Note:

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

### Return Values

Returns a new DateTime instance. Procedural style returns `FALSE` on failure.

### Errors/Exceptions

Emits Exception in case of an error.

### Changelog

Version | Description
--- | ---
5.3.0 | If `time` contains an invalid date/time format, then an exception is now thrown. Previously an error was emitted.

### Examples

Example #1 DateTime::__construct() example

Object oriented style

`<?php
try {
$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
