ORA_ROWSCN is not same as SCN

Thanks for the tip.

ORA_ROWSCN of very old row might be too old to be a valid SCN.
In that case, using scn_to_timestam p will give error:

ORA-08181: specified number is not a valid system change number
ORA-06512: at "SYS.SCN_TO_TIM ESTAMP", line 1

But, in case of a very recent row, this will work....
