C# WinApp ผมจะใช้งาน backgroundWorker ร่วมกับ datetime ได้ยังไงครับ

        private void frmCheckFileLyrics_Load(object sender, EventArgs e)
        {
            CheckFileLyrSetting.startCounter = DateTime.Now.TimeOfDay.TotalSeconds;
            backgroundWorker1.RunWorkerAsync();
        }

        private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            Text = DateTime.Now.ToString();
        }

        private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            Text = DateTime.Now.ToString();
        }
