Available Clocks
----------------

[](#available-clocks)

### System Clock

[](#system-clock)

The system clock relies on the current system time. If the `timezone` parameter is not defined it uses the timezone from the `date_default_timezone_get` method.

```
use Tobento\Service\Clock\SystemClock;
use Psr\Clock\ClockInterface;

$clock = new SystemClock();

var_dump($clock instanceof ClockInterface);
// bool(true)
```

**With defined timezone parameter**

```
use Tobento\Service\Clock\SystemClock;
use DateTimeZone;

$clock = new SystemClock(
    timezone: 'UTC'
);

$clock = new SystemClock(
    timezone: new DateTimeZone('Europe/Berlin')
);
```

### Frozen Clock

[](#frozen-clock)

The frozen clock will always return the same date time, suitable for testing. If the `now` parameter is not defined it uses the current time of the [System Clock](#system-clock).

```
use Tobento\Service\Clock\FrozenClock;
use Psr\Clock\ClockInterface;

$clock = new FrozenClock();

var_dump($clock instanceof ClockInterface);
// bool(true)

// Modify the clock returning a new instance.
// Will accept all formats supported by DateTimeImmutable::modify()
$clockNew = $clock->modify('+30 seconds');

// With a new timezone returning a new instance.
$clockNew = $clock->withTimeZone(timezone: 'UTC');
```

**With defined now parameter**

```
use Tobento\Service\Clock\FrozenClock;
use Tobento\Service\Clock\SystemClock;
use Psr\Clock\ClockInterface;
use DateTimeImmutable;

$clock = new FrozenClock(
    now: new DateTimeImmutable()
);

// or from another clock:
$clock = new FrozenClock(
    now: new SystemClock()
);
```
