Selecting Records based on time?

I have a datetime column in my database that stores results as:

2011-08-16 14:00:23

I want to do a select statement from this table to find all the records that have been added in the last 5 minutes.

Any ideas?

use BETWEEN and put the earlier value first

WHERE datetimeadded 
  BETWEEN CURRENT_TIMESTAMP - INTERVAL 5 MINUTE
      AND CURRENT_TIMESTAMP
