php5 Time format issues between PHP4 and PHP5

PHP5 used on my computer.
PHP4 on the server.
Time on my own machine, 2008-2-14 14:56:29
Write the program and upload it, and it will turn into a string of numbers. 1202972189
Access for database.. Field default value Now()
Solution:
There is no problem. This number is the Unix timestamp, which represents the number of seconds from 1970-1-1 to the present. It generally needs to be formatted and displayed
date('Y-m-d',1202972189)
The result is 2008-02-14

The above has introduced the time format issues of php5, PHP4 and PHP5, including the content of php5. I hope it will be helpful to friends who are interested in PHP tutorials.
