Question

I would like to know what is the best statement to get the actual time and then calculate the difference between two times. Should I use datetime or timestamp?

Thanks

You can use datediff() or timediff() to calculate the difference between dates or times respectively. See the documentation here on how to use them:

http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html

For example:

SELECT DATEDIFF('2007-12-31 23:59:59','2007-12-30');

SELECT TIMEDIFF('2000:01:01 00:00:00', '2000:01:01 00:00:00.000001');
