sysUseUtcLeapOffsetEnable
Module: CM-SYSTEM-MIB
OID (symbolic): CM-SYSTEM-MIB::sysUseUtcLeapOffsetEnable
OID (numeric): 1.3.6.1.4.1.2544.1.12.2.1.5.6
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This attribute indicates whether to use the currentUtcLeapOffset in Announce message from PTP to get UTC time from TAI based timestamps in case we want DM/TWAMP timestamping based on UTC time. This attribute only works when PTP/TimeClock is configured as source of system time of day.
What is sysUseUtcLeapOffsetEnable?
This TruthValue determines whether the system applies the currentUtcLeapOffset carried in PTP Announce messages to convert TAI-based PTP timestamps into UTC time, specifically for DM/TWAMP timestamping, and only takes effect when PTP is the configured time source. An admin enables this when delay-measurement or TWAMP timestamps must be reported in UTC rather than raw TAI time. For example, an operator running TWAMP tests across a PTP-synchronized network would enable sysUseUtcLeapOffsetEnable so the measured timestamps align with UTC-based reporting used elsewhere in the network.
Examples
