DateTime

The Orkestra DateTime Component builds on top of cakephp/chronos which itself builds on top of nesbot/carbon in order to bring immutability to dates and times as the default. It provides the concept of a ClockInterface to be used in projects to get the time as an infrastructure concern instead of directly accessing time as well as providing Date(Time)Range implementations.

Installation

composer require morebec/orkestra-orkestra-datetime

Then ensure the composer autoloader is imported:

<?php
require 'vendor/autoload.php';

use Morebec\Orkestra\DateTime\ClockInterface;
use Morebec\Orkestra\DateTime\SystemClock;

/** @var ClockInterface $clock */
$clock = new SystemClock();
printf("Now: %s", $clock->now());

Usage

ClockInterface

The clock interface is used in order to centralize the location where the current date/time is fetched. In essence, doing things like DateTime::now() in arbitrary locations of the code makes it harder to test, and manipulate. Being an infrastructure related concept, it makes more sense to obtain the time from a Clock than being able to access it from anywhere.

This can allow to test the system in the past or future.

Here are the implementations of the ClockInterface:

  • SystemClock Implementation of the system clock based on the time of the system.
  • FixedClock Implementation of clock always returning the same fixed date time, to be used in unit tests for better control of time.
  • OffsetClock Clock that returns the date time from a specific defined offset at creation as if it were the current time. This is useful when we have to reverse in time or fast-forward in the future but still keep the clock running as the actual time passes.

For more information on the available functions of Date and DateTime, please refer to the documentation of cakephp/chronos.
