Comparing datetime Iso8601 with Mysql ODBC standard datetime

how is it possible to perform search into the DB where dates are stored
in the standard ODBC datetime format ‘YYYY-MM-DD HH:MM:SS’ with DateTime
objects using the ISO8601 standard ‘YYYY-MM-DDTHH:MM:SSZ’… ? it’s a
big mess… what are the RoR recommendations ?

thanks a lot
