                   end_time End_Time, hexa_resol Hexa_Sol_Prep, hexa_used Hexa_Used, batch_coated Coated_Batch, resin_used Resin_Used, sand_quantity Make

                   where date='" & Format(CDate(sanddate.Text), "MM/dd/yyyy") & "' and shift='" & rblshift.SelectedValue & "' "
Using sda As New SqlDataAdapter()
   sda.SelectCommand = cmd

       sda.Fill(dt)

       vw_sand_details.DataBind()
   End Using
End Using

Answer

SELECT CONVERT(VARCHAR(5), GETUTCDATE(), 108)

will return the output in HH:MM format as 07:26

So in your query

SELECT CONVERT(VARCHAR(5), start_time, 108) 

will return the datetime into HH:MM format
