在laravel 5.4中有没有办法跟踪登录用户花费了多少时间？

use Illuminate\Auth\Events\Login;
use Illuminate\Support\Facades\Event;

public function boot()
{
    parent::boot();

    Event::listen(Login::class, function ($event) {
        $event->user->last_login_at = now();
        $event->user->save();
    });
}

protected $fillable = [
    // 其他字段...
    'last_login_at',
];

use Illuminate\Support\Facades\Auth;

// 获取当前登录用户
$user = Auth::user();

// 获取最后登录时间
$lastLoginTime = $user->last_login_at;

// 计算花费的时间
$spentTime = $lastLoginTime->diffInSeconds(now());
