I don't know why the displayed time in my Ubuntu 20.04 is different from real clock. As you can see below, I have synchronized the clock and then date
command shows it is 02:54:49 PM CEST
, but the query time from internet shows 10:55:18 UTC
. Since CEST is +2 hours ahead, the correct CEST time should be 10+2=12 AM and my watch shows this time, too.
$ sudo hwclock --systohc
$ timedatectl status

Any idea on how to fix that?
UPDATE:
On the system, chrony is running while ntp is masked.
$ dpkg -l | grep ntp
rc ntp 1:4.2.8p12+dfsg-3ubuntu4.20.04.1 amd64 Network Time Protocol daemon and utility programs
ii ntpdate 1:4.2.8p12+dfsg-3ubuntu4.20.04.1 amd64 client for setting system time from NTP servers (deprecated)
ii sntp 1:4.2.8p12+dfsg-3ubuntu4.20.04.1 amd64 Network Time Protocol - sntp client
$ dpkg -l | grep chrony
ii chrony 3.5-6ubuntu6.2 amd64 Versatile implementation of the Network Time Protocol
$ systemctl status ntp.service
● ntp.service

$ systemctl status chronyd.service

So, it seems that ntp is replaced by chrony on the system (Don't remember about that). But I don't know how to sync the chrony.
