MySQL: Delete all rows older than 10 minutes

I have a timestamp field in my table. How do I delete records older than 10 minutes old?

Tried this:

DELETE FROM locks WHERE time_created < DATE_SUB( CURRENT_TIME(), INTERVAL 10 MINUTE)

Didn't work. What am I doing wrong?

EDIT: I used this code:

SELECT time_created, CURRENT_TIMESTAMP, TIMESTAMPDIFF( MINUTE, time_created, CURRENT_TIMESTAMP ) FROM locks

But oddly, this gives the wrong result too

time_created         CURRENT_TIMESTAMP      TIMESTAMPDIFF( MINUTE, time_created,     CURRENT_TIMESTAMP )
2010-08-01 11:22:29   2010-08-08 12:00:48   10118
2010-08-01 11:23:03   2010-08-08 12:00:48   10117
