Description: Juniper Networks MIB for monitoring system timing, clock source selection, and synchronization on Juniper E-series routers.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is Juniper-System-Clock-MIB?
Juniper-System-Clock-MIB is a Juniper Networks enterprise MIB for the E-series router platform covering system clock/date-time configuration and Network Time Protocol (NTP) client/server management per RFC 1305. It exposes the current system date/time, timezone name, and detailed daylight-saving-time (DST) rules including recurring or absolute start/stop schedules. This MIB primarily supports software/configuration status monitoring: confirming the router's system clock and timezone are correctly set matters because accurate timestamps underpin correlating log/trap/event data across a network, and incorrect DST or clock settings can cause scheduling and certificate-validation issues. It explicitly depends on RFC 1305 (NTPv3) semantics for its NTP-related objects. It's deployed on Juniper E-series routers in service-provider and enterprise networks where accurate, synchronized system time is required for logging, security, and scheduled operations. Engineers can download the Juniper-System-Clock-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in Juniper-System-Clock-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Juniper Networks E-series routers
Monitoring Examples
An admin polls juniSysClockDateAndTime and juniSysClockTimeZoneName to confirm the router's clock and timezone are correct, and checks juniSysClockDstStatus along with juniSysClockDstAbsoluteStartTime/StopTime or the recurring juniSysClockDstRecurStartMonth/Week/Day/Hour/Minute objects to verify DST transitions ahead of a seasonal change. A router whose juniSysClockDateAndTime has drifted significantly from NTP reference time would indicate an NTP sync failure worth investigating via the juniNtpObjects branch.
What Can Be Monitored
- system date/time
- timezone setting
- DST status and schedule
- NTP synchronization

| I32 juniNtpSysClockFrequencyError | 1.3.6.1.4.1.4874.2.2.56.2.1.3 | Integer32 | read-only | 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 0.864 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.

If the Network Time Protocol (NTP) is enabled, attempts to set this object will result in an inconsistantValue error. For sets, the implementation may check the value of the year and if it is outside of a 'reasonable' range (e.g., 1999..2035) it may return an inconsistantValue error. Only system clock time and date will be set if the timezone offset is not set along with the timezone name. |
