APAR status

• Closed as program error.

Error description

• Reports in TPC Standalone GUI show a spike assocated to the time
  roll back, in addition 1 AM time is presented twice in the
  associated time scale.  Alerts were generated when values spiked
  above threshold for SVC and V7000 Devices.
