I'm assuming this is with the default chrony configuration, which uses the rtcsync directive. Please let me know if chrony is configured with the rtcdrift directive instead, that would be a different bug. With rtcsync, chronyd only tells the kernel that the system clock is synchronized and it's up to the kernel to correct the RTC. Unfortunately, the kernel doesn't care about timezones or DST and it's not able the fix the one hour error. This used to be handled by synchronizing the RTC from system clock on every shutdown/reboot, but that was for some strange reasons removed. Please see the bug #816752. adjtimex is a system call and also a package which uses the system call. chrony cares only about the system call, which is always present (it's in the kernel). *** This bug has been marked as a duplicate of bug 816752 *** The chronyd configuration file is /etc/chrony.conf. http://chrony.tuxfamily.org/manual.html#Configuration-file 4.2.41 rtcsync http://chrony.tuxfamily.org/manual.html#rtcsync-directive |
