Displaying data in the gridview from the database and adding extra column to it
<p>I'm trying to display data in the grid view that are stored in the database. Also, I'm trying to insert the time in the database when the data are entered. And finally, I want to add an extra column in the grid view which will display the time difference between the data entered and the data displayed. I can enter the time in the database and display it in the grid view, but I'm not able to calculate the time difference. Please help me with this.</p>

<p>Thanx in advance.</p>
