Issue Description

The Network Interpretations Team (NIT) has issued a technical decision regarding auditing of NTP Time Changes in the NDcPP v1.0 and FW cPP v1.0

Resolution

To align with NIT interpretation # 201658,

All discontinuous time changes, administrator actuated or changed via an automated process, must be audited. No audit is needed when time is changed via use of kernel or system facilities – such as adjtime(3) – that exhibit no discontinuities in time.

For further information, please see the NIT interpretation at: https://www.niap-ccevs.org/Documents_and_Guidance/ccevs/NITDecisionRfi201658.pdf.

Justification

See issue description.
