Gus, As far as I can remember, I have never seen anything but an ugly to_date('19700101', 'YYYYMMDD') + :unix_timestamp / 86400 Not really implicit. -- Stephane Faroult RoughSea Ltd <http://www.roughsea.com> Konagora <http://www.konagora.com> RoughSea Channel on Youtube <http://www.youtube.com/user/roughsealtd> > I would have thought that somewhere deep in the bowels of all the ancestor > versions of Oracle there would have been an implicit conversion of "epoch > time" to DATE data type. If it is there, how would it be invoked? > Regards, > > Gus > > > -- > //www.freelists.org/webpage/oracle-l > > > -- //www.freelists.org/webpage/oracle-l
