PSR Clock
This repository holds the interface for PSR-20.
Note that this is not a clock of its own. It is merely an interface that describes a clock. See the specification for more details.
Installation
composer require psr/clock
Usage
If you need a clock, you can use the interface like this:
<?php
use Psr\Clock\ClockInterface;
class Foo
{
private ClockInterface $clock;
public function __construct(ClockInterface $clock)
{
$this->clock = $clock;
}
public function doSomething()
{
/** @var DateTimeImmutable $currentDateAndTime */
$currentDateAndTime = $this->clock->now();
// do something useful with that information
}
}
You can then pick one of the implementations of the interface to get a clock.
If you want to implement the interface, you can require this package and
implement Psr\Clock\ClockInterface in your code.
Don't forget to add psr/clock-implementation to your composer.jsons provides-section like this:
{
"provides": {
"psr/clock-implementation": "1.0"
}
}
And please read the specification text for details on the interface.
