I am trying to determine when I added a few column to some tables. I know the columns but not when I added them...
Is there a way to easily determine the date the column was added? I don't see anything in DBA_TAB_COLUMNS.
I do do daily exports, I hope not to have to compare the dmp files.

may be you could check last_ddl in dba_objects, just an suggestion

i think i got my own answer, but for anyone's interest...
I uncompress my daily .dmp... I did the following (Unix only)
strings day_15.dmp | grep "CREATE TABLE" > 15.txt
strings day_22.dmp | grep "CREATE TABLE" > 22.txt
diff 15.txt 22.txt
that's it... I then see what was different.
good luck.
