EventSauce Clock

This is the EventSauce Clock component, which provides a straight forward way to consume time. Using a clock makes your code easier to test.

Installation

composer require eventsauce/clock

Usage

This package provides two implementations of the EventSauce\Clock\Clock interface.

---

In your production configuration, use the EventSauce\Clock\SystemClock implementation.

<?php

use EventSauce\Clock\SystemClock;

$clock = new SystemClock(new DateTimeZone('UTC') /* timezone optional */);

$dateTimeImmutable = $clock->now();
$timezone = $clock->timeZone();

In your test configuration, use the EventSauce\Clock\TestClock implementation.

<?php

use EventSauce\Clock\TestClock;

$testClock = new TestClock();
$dateTimeImmutable = $testClock->now();
$timezone = $testClock->timeZone();

// move the clock forward
$testClock->moveForward(DateInterval::createFromDateString('1 day'));

// Skip to system "now"
$testClock->tick();

// Fixate the clock to a specific date and time
$testClock->fixate('1987-11-24 18:33:10');
