"4:00 PM"
"12/30/1899 4:00 PM"

But i need this one only "4:00 PM"


so it was also showing the default date , i had tried a lot but no use i show my sample code

OleDbConnection cnCSV = new OleDbConnection(strConnectionString);
               cnCSV.Open();
               OleDbCommand cmdSelect1 = new OleDbCommand(@sgh, cnCSV);
               OleDbDataAdapter daCSV = new OleDbDataAdapter();
               daCSV.SelectCommand = cmdSelect1;
               DataSet ds = new DataSet();
               DataTable dtCSV1 = new DataTable();
               daCSV.Fill(dtCSV1);
               daCSV.Fill(ds, comboBox1.SelectedItem.ToString());
               daCSV = null;
               cnCSV.Close();
