Handing ATS/RIS files on CDR

Informix Gurus, May be the second time i'm sending this.... I just would like to know, as a DBA, what do you do with the ATS/RIS files. Are they just informational files??... just discard it or.... Is there any specific way to implement different time zones, if the ER servers are located at different time zones... like say PDT and EDT ( using CLU ) Thanks in advance, Dhanesh ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
