Juniper-System-Clock-MIB ·
.1.3.6.1.4.1.4874.2.2.56.2.1.3
Object
Displays the system clock frequency error in parts per million (ppm).
It will always be a positive value. This error adjustment happens when
the system reboots or the NTP is enabled for the first time and it may
take up to fifteen minutes to complete.
Each system clock oscillator interrupts to update its clock. If, for
example, it interrupts one million time per second then it has a
resolution of microseconds. This is also the frequency of the clock
update. Frequency error means that this system clock failed to update
by parts per millionth of a second.
For example, if the frequency error is 1ppm, it means the clock is ahead
by 0.0864 second in a day, and therefore the clock will need to be
corrected by that amount in the next 24 hours for the clock to be
accurate.
The frequency error varies with temperature. Therefore the system clock
will usually need to be corrected when the system boots, based on the
temperature at which it is operating.
