This is because the time that PHP takes is Greenwich mean time, so and your local time will be difference between Greenwich Mean time and Beijing time is about 8 hours, we can follow the following method to solve:

1, in the header using Date_default_timezone_set () set my default time zone for Beijing, that is, <?php date_default_timezone_set ("PRC");?> on it.

2, in the php.ini set the value of Date.timezone for the PRC, set the following as: DATE.TIMEZONE=PRC, while canceling this line of code comments, that is, remove the semicolon on the front can be.

Here's how to fix the problem by modifying the configuration file:

Open php.ini with notepad++,

Find "Date.timezone", remove the semicolon before the statement, set the value to "PRC", restart the fastcgi service, solve the problem
