•
ntpSysPrecision : signed integer indicating the precision of the various clocks, in seconds to the
nearest power of two.
•
ntpSysRootDelay : the total roundtrip delay to the primary reference source at the root of the
synchronization subnet, in seconds.
•
tpSysRootDispersion : the maximum error relative to the primary reference source at the root of
the synchronization subnet, in seconds. Only positive values greater than zero are possible.
•
ntpSysRefId : the particular reference clock. In the case of stratum 0 (unspecified) or stratum 1
(primary reference source), this is a pour-octet, left-justified, zero-padded ASCII string. In the case of
stratum 2 and greater (secondary reference) this is the four-octet Internet address of the peer selected
for synchronization.
•
ntpSysRefTime : the local time when the local clock was last updated. If the local clock as never
been synchronized, the value is zero.
• ntpSysPoll : the minimum interval between transmitted messages, in seconds as a power of two. For
instance, a value of six indicates a minimum interval of 64 seconds.
•
ntpSysPeer : the current synchronization source. Usually this will be a pointer to a structure contain-
ing the peer variables. The special value NULL indicates there is no currently valid synchronization
source.
•
ntpSysPhase : The system clock offset per selected source. (needs verification)
•
ntpSysFreq : The system clock frequency correction per ntpd. (needs verification)
•
ntpSysError : The current system error per ntpd? (needs verification)
•
ntpSysClock : the current local time. Local time is derived from the hardware clock of the particular
machine and increments at intervals depending on the design used.
• ntpSysSystem : the type of local Operating System.
• ntpSysProcessor : the type of the local Processor.
