Ich möchte das überschreibentimestamps() Funktion in der gefundenBlueprint Klasse. Wie kann ich das machen?

z.B.,

public function up() {
    Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->string('username')->unique();
        $table->string('password');
        $table->string('email');
        $table->string('name');
        $table->timestamps(); // <-- I want this to call my method instead of the one found in the base Blueprint class
    });
}
