How to subtract hours from a datetime in MySQL?

Question

I get a datetime field, that\'s currently in the query as:

SELECT DATE_FORMAT(x.date_entered, \'%Y-%m-%d\') AS date FROM x ORDER BY date ASC

<

Answer 1

mySQL has DATE_SUB():

SELECT DATE_SUB(column, INTERVAL 3 HOUR)....

but would it not be better to try and sort out the underlying time zone issue instead?
