usdNtpSysClockOffsetError
Module: Unisphere-Data-System-Clock-MIB
OID (symbolic): Unisphere-Data-System-Clock-MIB::usdNtpSysClockOffsetError
OID (numeric): 1.3.6.1.4.1.4874.2.2.56.2.1.2
Node type: OBJECT-TYPE
Type: UsdNtpClockSignedTime
Access: read-only
Description: Displays the estimated offset error of the system clock relative to the master clock in seconds. This variable can take on both positive and negative values; the value will be positive if the system clock is ahead of the master clock; the value will be negative if the system clock is behind the master clock. This offset value will be used by internal the NTP filter algorithm to adjust the system clock to correct its error.
What is usdNtpSysClockOffsetError?
The estimated offset, in seconds, between the local system clock and the master NTP clock; positive means the local clock is ahead, negative means it is behind. This value feeds the internal NTP filter algorithm that corrects the clock, so admins watch it to confirm sync accuracy is converging toward zero.
