PHP has a very powerful function for time operations. When you stock time information to the data, you typically save a timestamp.

Time Origin: The computer world is set to January 1, 1970 0:0 0 seconds, the time origin

Timestamp: From the time origin to the current number of seconds (JS is the number of milliseconds).

Time zone settings:

Date_default_timezone_set (' PRC ');
