I have chrony running and pointing to my ISP's time server, not the Fedora pool, so it's always the same NTP server.
This box is up 24/7, and I just rebooted it. And I get this, after a reboot:
Nov 23 08:53:10 shorty chronyd[992]: System clock TAI offset set to 37 seconds Nov 23 08:53:10 shorty chronyd[992]: System clock wrong by -5.652285 seconds, adjustment started Nov 23 08:53:10 shorty chronyd[992]: System clock was stepped by -5.652285 seconds
This was a reboot, and not a shutdown.
I believe that something should be saving the system time to the hardware clock, so after a reboot things are more or less where they are, and this looks like is not happening. I should not have chrony adjust time by that much after a reboot. Anyone know where to investigate this further?
