In 9i you can look at the table smon_scn_time in the sys schema.  You can
view the times and scn's associated with them from there.  Instead of a
function, it is a table query.

Is scn_to_timestamp a version 10 specific function?  I do not find it in my
version 9.2.0.5 test system.

David,

These views/tables each have CORRUPTION_CHANGE# in them.  You could
use the SCN_TO_TIMESTAMP function to get the time that the corruption
was detected.

From the docs, this column stores the "Change number at which the
logical corruption was detected. Set to 0 to indicate media
corruption."

-Jamie

select scn_to_timestamp(1711819000) from dual;

SCN_TO_TIMESTAMP(1711819000)
