Incorrect Virtual Machine Time(CGP Virtualization)

Incorrect Virtual Machine Time(CGP Virtualization)

Symptom

  • ALM-5016 Failure in Time Synchronization Between the Board and OMU is displayed on the OMU client.
  • The time displayed in the call detail record (CDR) is incorrect. For example, the end time of a call is earlier than the start time.
  • In the traffic measurement result, the value in the Credible column is Incredible because of time transition.
  • The time on the board running services is inconsistent with the time on the OMU. For example, when you run DSP INTIME in the MML Command - CGP window to query the System time of each board. The System time of each board or the time on a board is more than 2 seconds earlier or later than the OMU time displayed in the command output.
