在Laravel 5.8版中，我使用maatwebsite打包（3.0版）导入excel工作表，但它无法导入数据时间字段

我正在使用laravel 5.8 vertion和maatwebsite包导入数据表，无法将datatime字段作为日期和时间导入。它是零，如0000-00-00 00:00:00。我想获得时间和时间之间的差异。请帮助我将excel报告添加到我的数据库中，并将时间和日期作为单独的变量获取差异，我如何处理数据库中的时间和日期？ 我试过了

///////////// 我的控制器

namespace App\Http\Controllers;

use App\Attendance;
use App\Employee;
use App\Imports\UsersImport;
use App\Exports\UsersExport;
use Maatwebsite\Excel\Facades\Excel;

class AttenadanceController extends Controller
{
    public function Index()
    {
      $dataAttendance = Attendance::latest()->paginate(10);

//      $empId = Attendance::select('emp_id')->get();
//      $employee = Employee::where('employee_id',$empId)->first();

//        return response()->json($empId);
      return view('attendance.attendance',['title' => 'Attendance'])->with('data',$dataAttendance);
    }
//from FORM
    /**
     * @return \Illuminate\Http\RedirectResponse
     */
    public function importExcel()
    {
            Excel::import(new UsersImport, request()->file('file'));
            return redirect()->back();
    }

//from DB
    public function exportExcel()
    {
        Excel::download(new UsersExport, 'new.xlsx');
    }
}
