Re: Effect on Oracle of changing server time from EST to GMT
Good point, Dan. If using SCN to flashback then it's a non-issue. Avoid using date/time stamp to flashback during that 1 hour period. Or find out the SCN from SYS.SMON_SCN_TIME table closest to the past time, and use it to flashback. - Kirti --- Daniel Fink [EMAIL PROTECTED] wrote: Another thought for 9i...how would a time change impact flashback query?

Guiness Mean Time will not have effect on the time recorded in the database, just how it is displayed.
