I wish to display the starting time and date of up-to-date row from MySQL to wordpress site. How do i do this?

Supposing that you would like to show the date/time the publish was modified, take a look in the link below.

// Displays the date and time.

<p>Modified: <?php the_modified_date('F j, Y'); ?> at <?php the_modified_date('g:i a'); ?></p>
