Is it possible to calculate difference between two timestamps in Mysql and get output result in seconds? like 2010-11-29 13:16:55 - 2010-11-29 13:13:55 should give 180 seconds.<
TIMESTAMPDIFF method only works with datetime format. If you want the difference between just two times like '11:10:00' minus '10:20:00' then use
select TIME_TO_SEC('11:10:00')-TIME_TO_SEC('10:20:00')
