It tells you the minimum time to rollforward this tablespace
during tablespace recovery.

The minimum recovery time guarantees that after a point-in-time
restore of this tablespace it will be in sync with the
syscatspace.
Creating tables, dropping tables or altering tables for
example will set the minimum recovery time on a tablespace
or altering some characteristic of the tablespace itself will
also set this time.

The minimum recovery time is not set for the syscatspace
(because you can't recover this tablespace to a point-in-time)
or for temporary tablespaces. It might also not be set because
you never changed the definition of a table (create/alter/drop)
or of this tablespace.

HTH.

Best regards

Eric
