Item

Underflow or Overflow appears in this column if an invalid time stamp is detected. If
Underflow appears, the time stamp is below the allowable range. If Overflow appears, the
time stamp is above the allowable range.

The consistency time is valid only for the updates on the Cnt Ac-J Z pairs in Duplex status.
When the data of the Cnt Ac-J Z pair that is in other than Duplex status is updated, the
consistency time is not assured. Therefore, even if the journal of the Cnt Ac-J Z pair that shares
the volume with BC Z or Cnt Ac-S Z is registered to the EXCTG, the consistency time is invalid
if the Cnt Ac-J Z pair is in other than Duplex status or if the BC Z or Cnt Ac-S Z pair is updated.
The consistency time is invalid also when the data is updated without the time stamp from
the host computer.
