About the processing of date() warning reported by PHP program (date_default_timezone_set)_PHP tutorial
Sometimes this warning will appear when writing PHP programs:
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 ewsfile.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 solve it according to the following method:
1. Use date_default_timezone_set() on the header of the page to set my default time zone to Beijing time, that is, That's it.
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. At the same time, uncomment this line of code, that is, remove the preceding one. The semicolon is fine.
Then restart apache!

Introduction to methods and usage of using Date and SimpleDateFormat classes to process time in Java
Apr 21, 2023 pm 03:01 PM
1. Introduction The Date class in the java.util package represents a specific time, accurate to milliseconds. If we want to use our Date class, then we must introduce our Date class. Writing the year directly into the Date class will not produce the correct result. Because Date in Java is calculated from 1900, so as long as you fill in the first parameter with the number of years since 1900, you will get the year you want. The month needs to be subtracted by 1, and the day can be inserted directly. This method is rarely used, and the second method is commonly used. This method is to convert a string that conforms to a specific format, such as yyyy-MM-dd, into Date type data. First, define an object of Date type Date
