A PHP Trait for Laravel Applications to disable the `updated_at` attribute on Models. It should be used if you only have a `created_at` column but not a `updated_at` column. https://stefanzweifel.io/posts/disableupdatedat-trait-for-laravel-5-4

DisableUpdatedAt.php

<?php

namespace App\Traits;

/**
 * This Trait disabled the updated_at value for a model.
 * Laravel doesn't provide an easy way to to this.
 * The framework **alyways** tries to append the updated_at column
 * when the `$timestamps` property is not set to false.
 * See code here: https://github.com/illuminate/database/blob/5.4/Eloquent/Builder.php#L757-L760.
 *
 * This traits disables all timestamps (including created_at) when performing
 * an update. We do this by listening to the `updating` and `updated`
 * events.
