While chronyd is running with the rtcfile directive, timedatectl shows
$ timedatectl
Local time: Fri 2024-08-09 14:12:01 UTC
Universal time: Fri 2024-08-09 14:12:01 UTC
RTC time: n/a
Time zone: Universal (UTC, +0000)
System clock synchronized: yes
NTP service: active
RTC in local TZ: no
When using chronyc's rtcdata command, you get
RTC ref time (GMT) : Sat May 30 07:25:56 2015
Number of samples : 10
Number of runs : 5
Sample span period : 549
RTC is fast by : -1.632736 seconds
RTC gains time at : -107.623 ppm
where
RTC ref time (GMT)
This is the RTC reading the last time its error was measured.
so this is not the current RTC value either. How to read it out then without having to stop chronyd?
