PHP timestamp time zone is generally set or not set?

When you do the PHP program, the php.ini or the program itself when the time stamp used to set the timezone is not set by default or set to the East eight district of Shanghai, Asia?

the timestamp is always UTC.

local time to see the need. If your application involves multiple time zones, you should actually encapsulate the time-related things in your PHP program and not rely on PHP's time zone settings

Should be the Date_default_timezone_set to be set ("Asia/shanghai");
