Hi,
To get the Current Time u can use DateTime.Now property. It returns CurrentTime. So in btnStart u can use like this

c# Syntax (Toggle Plain Text) 
  1.      private void btnStart_Click(object sender, EventArgs e)
  2.     {
  3.         //Display the current Time
  4.         textBox1.Text = DateTime.Now.ToString("hh:mm:ss tt");
  5.         textBox2.Text = DateTime.Now.ToString("hh:mm:ss tt");
  6.         //Start the Timer
  7.         tmrTime.Enabled = true;
  8.     }

Be sure to have three TextBoxes (textBox1, textBox2, textBox3)

C# Syntax (Toggle Plain Text) 
  1. DateTime.Now.ToString (String s)
Provides you to format the Time
like hour : min : secs

Draw a Timer controls and Make Enable property to false, Interval Property to 1000 and Add TimerTick handler

C# Syntax (Toggle Plain Text) 
  1.     private void tmrTime_Tick(object sender, EventArgs e)
  2.     {
  3.         //Periodically update the values
  4.         textBox2.Text = DateTime.Now.ToString("hh:mm:ss tt");
  5.     }

This again change the time to DateTime variables.

At last Display the different in TextBox3
and Stop the timer
C# Syntax (Toggle Plain Text) 
  1.     private void btnStop_Click(object sender, EventArgs e)
  2.     {
  3.         DateTime dateTime1, dateTime2;
  4.         // Change Time String to DateTime object
  5.         dateTime1 = DateTime.Parse(textBox1.Text);
  6.         dateTime2 = DateTime.Parse(textBox2.Text);
  7.         //Find the Difference
  8.         TimeSpan timeDiff = dateTime2.Subtract(dateTime1);
  9.         //Display the Difference
  10.         textBox3.Text = timeDiff.ToString();
  11.         //Stop the Timer
  12.         tmrTime.Enabled = false;
  13.     }

Why did you do the guys homework for him? A simple textBox2.Text = dateTime.ToString("hh:mm:ss tt"); would have sufficed.

All you do by doing someone's homework for them is encourage more of those kinds of questions without them putting any effort at all to at least take a stab at it.

i have textbox,listbox and a button.i want when i enter a date in textbox.the specified data in listbox is displayed which is from a log file.Now.I want only when i select a current time,only the output data is displayed,not all teh data which displayed before
here is the code for the button to display the data.
C# Syntax (Toggle Plain Text) 
  1. if (BioBridgeSDK.ReadGeneralLog(ref log) == 0)
  2.             {
  3.                 while (BioBridgeSDK.GetGeneralLog(ref EnrollNo, ref yr, ref mth, ref day_Renamed, ref hr, ref min, ref sec, ref ver, ref io, ref work) == 0)
  4.              <span class="ad_notxt"><code class="inlinecode">     //read the information logs from the memory buffer</code></span> {
  5. if (io == 0)
  6.                         {
  7.  
  8.                            listBox2.Items.Add(("No: " + Convert.ToString(EnrollNo) + " Date:" + Convert.ToString(day_Renamed) + "/" + Convert.ToString(mth) + "/" + Convert.ToString(yr) + " Time: " + Convert.ToString(hr) + ":" + Convert.ToString(min) + ":" + Convert.ToString(sec) + " I/O: Check In"));
  9.                             //listBox2.Items.Add(textBox2.TextChanged);
  10.                         }
  11.                         else
  12.                             listBox2.Items.Add(("No: " + Convert.ToString(EnrollNo) + " Date:" + Convert.ToString(day_Renamed) + "/" + Convert.ToString(mth) + "/" + Convert.ToString(yr) + " Time: " + Convert.ToString(hr) + ":" + Convert.ToString(min) + ":" + Convert.ToString(sec) + " I/O: Check Out"));
  13.                        // if (textBox2.Text = DateTime())
  14. {
  15.  
  16.  
  17. }
i dont know what to write in order to make the selected date to appear the specified log.Also,do i need textBox2_TextChanged
to be fired each time i change teh date in the textbox or not?.

Thanks,
