IntlCalendar::fromDateTime — Create an IntlCalendar from a DateTime object or string
Описание
Объектно-ориентированный стиль
Процедурный стиль
Creates an IntlCalendar object either from a DateTime object or from a string from which a DateTime object can be built.
The new calendar will represent not only the same instant as the given DateTime (subject to precision loss for dates very far into the past or future), but also the same timezone (subject to the caveat that different timezone databases will be used, and therefore the results may differ).
Список параметров
-
dateTime -
A DateTime object or a string that can be passed to DateTime::__construct().
Возвращаемые значения
The created IntlCalendar object or NULL in case of
failure. If a string is passed, any exception that occurs
inside the DateTime constructor is propagated.

//Note the timezone is Europe/Berlin, not the default Europe/Lisbon
echo IntlDateFormatter::formatObject($cal1, 'yyyy MMMM d HH:mm:ss VVVV', 'de_DE'), "\n";

Don't forget that fromDateTime() doesn't set any locale and that the default one will be set. In my case it was en_US_POSIX.
If you wan't to create a IntlCalendar object containing the values of a DateTime object with your locale, use createInstance() instead and do a
<?php
$intlCalendar->setTime($dateTime->getTimestamp() * 1000);
?>
IntlCalendar works with milliseconds so you need to multiply the timestamp with 1000.
Using fromDateTime() can cause unwanted behaviour like getFirstDayOfWeek() returning a wrong integer.
