ieee8021AsDefaultDSLeap59

Module: IEEE8021-AS-MIB

OID (symbolic): IEEE8021-AS-MIB::ieee8021AsDefaultDSLeap59

OID (numeric): 1.3.111.2.802.1.1.20.1.1.11

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-only

Description: A true (1) value indicates that the last minute of the current UTC day, relative to the ClockMaster entity of this time-aware system, will contain 59 seconds. It is equal to the global variable sysLeap59 (see 10.3.8.12).

The initialization value is selected as follows: a) Set to true (1) if the value is obtained from a primary reference if known at the at the time of initialization, else b) The value is set to false (2).

What is ieee8021AsDefaultDSLeap59?

True if the current UTC day, as tracked by this device, ends with a 59-second last minute (a negative leap second). Relevant only around a scheduled leap-second event, to confirm the device is aware of it.

Examples
