The time () function generates a long string of numbers representing how many seconds have passed since January 1, 1970. It is possible to add and subtract time by adding and subtracting seconds.

<?php
$b = time () - 3600;
print date("D, F jS G:i a",$b) . "<br>";
?>


You can add or subtract any amount of seconds to the time function while you create it's variable. This let's you offset minutes, hours, days or even years.
