This article explains the solution to the date() warning reported by the PHP program.

PHP Warning: date(): It is not safe to rely on the system's timezone settings. You are required to use the date.timezone setting or the date_default_timezone_set() function

Writing PHP Sometimes such warnings appear in the program:

PHP Warning: date(): It is not safe to rely on the system's timezone settings. You are required to use the date.timezone setting or the date_default_timezone_set() function . In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'UTC' for '8.0/no DST' instead in D:\PHPWEB ews\file.php on line 17.

This is because the time taken by PHP is Greenwich Mean Time, so it will be different from your local time. The difference between Greenwich Mean Time and Beijing time is about 8 hours. We can follow the following Solution:

1. Use date_default_timezone_set() in the header to set my default time zone to Beijing time, that is,

<!--?php
    date_default_timezone_set("PRC");
?-->

.

2. Set the value of date.timezone in php.ini to PRC. After setting, it will be: date.timezone=PRC or date.timezone = Asia/Shanghai, and uncomment this line of code. That is, just remove the preceding semicolon.

Then restart apache!
