This is a DateTime package built for the Joomla! Framework during Google Summer of Code 2014. The main goal for this library was to create a DateTime object as an Immutable Value Object.

If you know how to use PHP DateTime object then you know almost everything about that package. Before you start using it you need to know one more thing - this DateTime is immutable. To explain what immutability means let's take a look at an example:

$start = new DateTime('2014-08-24');
$end = $start->addDays(2);

echo $start->format('Y-m-d');  // 2014-08-24
echo $end->format('Y-m-d');    // 2014-08-26

Every method of DateTime is returning a new object and is not changing the current one. That's the most important thing what you have to know.

• Date & DateTime
• DateRange & DateTimeRange
• DateInterval
• GetterInterface
• ParserInterface
• SinceInterface
• AbstractTranslator
• StrategyInterface

Jens Segers for their approach to translations

Add "joomla/datetime": "~2.0" to the require block in your composer.json and then run composer install.

{
	"require": {
		"joomla/datetime": "~2.0"
	}
}

Alternatively, you can simply run the following from the command line:

composer require joomla/date "~2.0"
