How to Disable Daylight Savings Time on RedHat 9.0

We have created a MySQL/ C application that gathers environmental data and does inserts into the db once per minute. A set of PHP applications reads this data and does some graphical display of the values. Changing from Standard Time to Daylight Savings Time causes minor problems, but in the Fall, DST to ST will screw things up royally. I did some googling yesterday, and others have asked how to disable the automatic DST changeover in Red Hat 9.0, but no one really got an answer, leading me to believe that it is not straight forward. Does anyone know how to do this?? Thanks very much, David
