IntlCalendar::toDateTimeConvert an IntlCalendar into a DateTime object


Object-oriented style

public IntlCalendar::toDateTime(): DateTime|false

Procedural style

intlcal_to_date_time(IntlCalendar $calendar): DateTime|false

Create a DateTime object that represents the same instant (up to second precision, with a rounding error of less than 1 second) and has an analog timezone to this object (the difference being DateTimeʼs timezone will be backed by PHPʼs timezone while IntlCalendarʼs timezone is backed by ICUʼs).



An IntlCalendar instance.

Return Values

A DateTime object with the same timezone as this object (though using PHPʼs database instead of ICUʼs) and the same time, except for the smaller precision (second precision instead of millisecond). Returns false on failure.


Example #1 IntlCalendar::toDateTime()

('date.timezone', 'UTC');
ini_set('intl.default_locale', 'pt_PT');

$cal = IntlCalendar::createInstance('Europe/Lisbon'); //current time

$dt = $cal->toDateTime();

The above example will output:

DateTime Object
    [date] => 2013-07-02 00:29:13
    [timezone_type] => 3
    [timezone] => Europe/Lisbon
