I have a global database and we have implemented data types "timestamp with local time zones" This works great, clients inform the database which time zone their in and they get the correct time, My problem is day light savings. Do we move the database time a back an hour? We move the Host time clock back?? I don't really know what to do so the timestamps don't get messed up. Currently the server is off by an hour . and we don't know what to do or know the implications of any of our actions. ____________________________________________ Glen Bernas Database Administrator EMC² where information lives Phone: Direct: (508) 249-2237 Ext: 42237 -- //www.freelists.org/webpage/oracle-l
