Using label display timenow to mark checkbox(s)

I have a label on my webform which displays current system. I want to use the label displayed to mark automatically checkboxes if the time is greater than 9:30am.
Below is my code but am having the following error message:

The best overload method match for system timespan(long) has some invalid arguments.

See my codes below:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {

         if (e.Row.RowType == DataControlRowType.DataRow)
    {
        CheckBox ChkBoxLate = e.Row.FindControl("ChkBoxLate") as CheckBox;
        TimeSpan time = TimeSpan.Parse(LblTimeNow.Text.Trim());
        TimeSpan timeToCompare = new TimeSpan(LblTimeNow);
        if (time > timeToCompare)
        {
            ChkBoxLate.Checked = true;
        }
    }
}

Thanks

Accepted answer
TimeSpan object expects a long value and yet you are passing the Label control that's why it errors.

Try this instead:

CheckBox ChkBoxLate = e.Row.FindControl("ChkBoxLate") as CheckBox;
DateTime timeNow;
DateTime timeToCompare = Convert.ToDateTime("09:30:00");
if (DateTime.TryParse(LblTimeNow.Text.Trim(), out timeNow))
{
if(timeNow.TimeOfDay > timeToCompare.TimeOfDay){
ChkBoxLate.Checked = true;
}
}
