Migration fields with timezones

Did you know that in migrations there's not only timestamps() but also timestampsTz(), for the timezone?

Schema::create('employees', function (Blueprint $table) {
    $table->increments('id');
    $table->string('name');
    $table->string('email');
    $table->timestampsTz();
});

Also, there are columns dateTimeTz(), timeTz(), timestampTz(), softDeletesTz().
