Immutable date and time for PHP with a convenient interface

Requirements

• PHP 5.6.0+

Installation

1. Include the library via Composer [?]:

   $ composer require delight-im/temporal
   

2. Include the Composer autoloader:

   require __DIR__ . '/vendor/autoload.php';

3. Make sure to set your default time zone in PHP, e.g.:

   \date_default_timezone_set('America/Los_Angeles');
