  • ONTAP 9
  • SnapMirror

Answer

  • Yes, the system time on both source and destination clusters must be correct to see valid lag time.
  • The lag time is calculated by the timestamp when the last transferred snapshot was created and the system time on the destination when the transfer completes
    • If system times are configured incorrectly, timestamps will be inaccurate
    • Inaccurate timestamps will result in an inaccurate lag time
