Hello, the following question arose, in the database you need to store the date and time (for example, 12:30:00 01-06-2012), then in the script you need to get the date of the person who entered, and subtract from the data from the database received from user data, and display the result according to the example: 2d. 14-30-45.
I turned the reference book, but something without results, tell me how to do this? In what format to store data in the database, how to perform an arithmetic operation on a date? I met an analogue on the site 2012god.ru (not advertising), they have a similar one in the header.
