<div dir="ltr">If ntpd or systemd-timesyncd is running, this makes perfect sense. Linux maintains current time in the kernel. The hardware RTC is only used to load an initial time at boot and is written during shutdown. When an NTP daemon is running and an NTP server is reachable, it will adjust the kernel's current time to match NTP time. I believe with timesyncd, it simply steps time instead of slewing like ntpd does.<div><br></div><div>What are you trying to accomplish?
