The option rtcfile in the default config conflicts with runit's stage 3. Chronyd in RTC mode takes control of /dev/rtc to measure RTC drift. Stage 3 calls hwclock -w, which messes up chrony's drift calculation. Furthermore the current chronyd runit service needs the -s option to effectively use the RTC feature. See for more info: https://chrony.tuxfamily.org/faq.html#_i_want_to_use_code_chronyd_code_s_rtc_support_must_i_disable_code_hwclock_code Switch rtcfile to the rtcsync option, to be consistent with stage 3. Example config file 1 sets the right options that work out of the box. So use that example file instead of editing the annotated one. Example config file 3 will instead be installed to /usr/share/examples.
