In this example time is function which echo out seconds from 1st January 1970 to today’s time seconds reached. Function returns current unit time stamps. As you can see output every time you refresh it will increase by seconds.So, its very useful to keep track of amount of second or current time depending upon you like if you want to track when the comment is posted when you posted on you post. But its not user-friendly because we are echoing the seconds not in human reader format.
