Time Stamp

Getting the Time Stamp with time()

PHP's time() function gives you all the information that you need about the current date and time. It requires no arguments but returns an integer.
The integer returned by time() represents the number of seconds elapsed since midnight GMT on January 1, 1970. This moment is known as the UNIX epoch, and the number of seconds that have elapsed since then is referred to as a time stamp.

<?php print time(); ?>

It will produce following result:

948316201

This is something difficult to understand. But PHP offers excellent tools to convert a time stamp into a form that humans are comfortable with.
