This is a custom package designed for Laravel Eloquent. It provides a trait that can be used in model classes that will cast datetime fields to ChronosInterface instead of Carbon instances.

Chronos is a drop-in replacement for Carbon but is immutable by default. It also provides an interface that can be used for some genericising as well.

See the [Chronos documentation](https://book.cakephp.org/3.0/en/chronos.html) for more information.

Usage
-----

[](#usage)

Warning

This package is not compatible with Laravel's attribute casts: immutable\_date, immutable\_datetime.

To convert datetime casts from Carbon instances to Chronos instances in an Eloquent model, all you need to do is `use`this trait in the model. An example is shown below:

```
use HealthEngine\LaravelChronos\ChronosTimestamps;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use ChronosTimestamps;

    protected $casts = [
        // Throws error: "Call to undefined method Cake\Chronos\Chronos::toImmutable()"
        // 'processed_at' => 'immutable_date',
        // Throws error: "Call to undefined method Cake\Chronos\Chronos::toImmutable()"
        // 'processed_at' => 'immutable_datetime',
        'processed_at' => 'datetime',
    ];
}
```
