This fix is aimed at The administrator changes the timezone to hide a several-minute clock error. and would be relevant if A systemd Linux host has the wrong system date even though its timezone setting is correct. The incident instead states The operator assumes every configured source is selected even though most are unreachable. and needs Use chronyc sources or tracking to identify the selected reference and failed reachability.

This fix is aimed at The clock is several hours ahead yet certificates are reissued rather than fixing time. and would be relevant if Two Linux nodes disagree about certificate validity because one has synchronized time and the other does not. The incident instead states The operator assumes every configured source is selected even though most are unreachable. and needs Use chronyc sources or tracking to identify the selected reference and failed reachability.

This fix is aimed at All timekeeping depends on one retired fixed address that no longer responds. and would be relevant if A small deployment needs multiple DNS-discovered public time servers with changing individual hosts. The incident instead states The operator assumes every configured source is selected even though most are unreachable. and needs Use chronyc sources or tracking to identify the selected reference and failed reachability.

Configure server or pool directives in the active chrony.conf and restart/reload chronyd appropriately. That operation is designed for the different case: An administrator needs to add approved chrony time sources to a host that uses chronyd. It does not perform the specific action required here: Use ntpq -p to inspect NTP peer associations where ntpd exposes that interface.

Synchronize the hardware clock from the known-correct system clock with hwclock --systohc, respecting the site's UTC convention. That operation is designed for the different case: A server's hardware RTC drifts away from the correct time stored in the Linux system clock. It does not perform the specific action required here: Use ntpq -p to inspect NTP peer associations where ntpd exposes that interface.

Run chronyc sources -v and inspect the source-selection marker and reachability. That operation is designed for the different case: A time-source investigation needs evidence of which chrony server is currently selected. It does not perform the specific action required here: Use ntpq -p to inspect NTP peer associations where ntpd exposes that interface.

This explains another Linux operation, namely Configure server or pool directives in the active chrony.conf and restart/reload chronyd appropriately., where chronyd reads its configured upstream NTP sources to discipline the local clock. It does not explain why Use ntpq -p to inspect NTP peer associations where ntpd exposes that interface. satisfies the stated condition.

This explains another Linux operation, namely Run chronyc sources -v and inspect the source-selection marker and reachability., where chronyc reports server state, while source selection is not established merely by seeing a DNS name in a configuration file. It does not explain why Use ntpq -p to inspect NTP peer associations where ntpd exposes that interface. satisfies the stated condition.

This explains another Linux operation, namely Use timedatectl or the appropriate privileged date mechanism to set the system clock, then restore NTP sync., where The real-time system clock and the timezone describe different things; changing the timezone cannot repair a wrong UTC instant. It does not explain why Use ntpq -p to inspect NTP peer associations where ntpd exposes that interface. satisfies the stated condition.

That observation checks A systemd Linux host has the wrong system date even though its timezone setting is correct. In this scenario it does not demonstrate Use ntpq -p to inspect NTP peer associations where ntpd exposes that interface.; the relevant evidence must establish The peer table reports a selected usable source and recent delay/offset measurements.

That symptom concerns A server's hardware RTC drifts away from the correct time stored in the Linux system clock. This concerns a separate requirement, not the one being tested. The relevant failure is The team runs chronyc on a host with ntpd only and receives no chronyd response. The current requirement calls for a different check.

This fix is aimed at The administrator changes the timezone to hide a several-minute clock error. and would be relevant if A systemd Linux host has the wrong system date even though its timezone setting is correct. The incident instead states The team runs chronyc on a host with ntpd only and receives no chronyd response. and needs Query ntpd with ntpq -p and verify the daemon identity first.

This fix is aimed at Only an obsolete ntp.conf file was edited, so the running chronyd still uses its old sources. and would be relevant if An administrator needs to add approved chrony time sources to a host that uses chronyd. The incident instead states The team runs chronyc on a host with ntpd only and receives no chronyd response. and needs Query ntpd with ntpq -p and verify the daemon identity first.

This fix is aimed at The system clock is corrected by NTP but the RTC still carries the old value across reboot. and would be relevant if A server's hardware RTC drifts away from the correct time stored in the Linux system clock. The incident instead states The team runs chronyc on a host with ntpd only and receives no chronyd response. and needs Query ntpd with ntpq -p and verify the daemon identity first.

Configure server or pool directives in the active chrony.conf and restart/reload chronyd appropriately. That operation is designed for the different case: An administrator needs to add approved chrony time sources to a host that uses chronyd. It does not perform the specific action required here: Use an approved pool.ntp.org pool directive with appropriate chrony/ntpd pool syntax.

Use timedatectl or the appropriate privileged date mechanism to set the system clock, then restore NTP sync. That operation is designed for the different case: A systemd Linux host has the wrong system date even though its timezone setting is correct. It does not perform the specific action required here: Use an approved pool.ntp.org pool directive with appropriate chrony/ntpd pool syntax.

Use ntpq -p to inspect NTP peer associations where ntpd exposes that interface. That operation is designed for the different case: A legacy host uses ntpd and the admin needs to view peer delay, offset and reachability. It does not perform the specific action required here: Use an approved pool.ntp.org pool directive with appropriate chrony/ntpd pool syntax.

This explains another Linux operation, namely Synchronize the hardware clock from the known-correct system clock with hwclock --systohc, respecting the site's UTC convention., where hwclock explicitly reads or writes the hardware real-time clock independently of the running system clock. It does not explain why Use an approved pool.ntp.org pool directive with appropriate chrony/ntpd pool syntax. satisfies the stated condition.

This explains another Linux operation, namely Configure server or pool directives in the active chrony.conf and restart/reload chronyd appropriately., where chronyd reads its configured upstream NTP sources to discipline the local clock. It does not explain why Use an approved pool.ntp.org pool directive with appropriate chrony/ntpd pool syntax. satisfies the stated condition.

This explains another Linux operation, namely Restore correct NTP/chrony clock discipline on the unsynchronized host before debugging certificate age., where Certificate validity checks depend on the current instant; a clock far in the past or future can cause false failures. It does not explain why Use an approved pool.ntp.org pool directive with appropriate chrony/ntpd pool syntax. satisfies the stated condition.

That observation checks A server's hardware RTC drifts away from the correct time stored in the Linux system clock. In this scenario it does not demonstrate Use an approved pool.ntp.org pool directive with appropriate chrony/ntpd pool syntax.; the relevant evidence must establish The synchronization service reports several usable upstream peers discovered through the pool.
