Re: [chrony-users] CEST time is not correct

[Bill Unruh <unruh@xxxxxxxxxxxxxx>]

I am not sure what you are worried about. system time and chrony time is ALWAYS UTC. it is
your computer which translates UTC to the local time when you ask it for the
time (eg using date). Is that what is confusing you?

Yes, you should NEVER have them running at the same time.

Not enough information.

Run chronyc as root and then give it the command 
tracking.

What does it say.

What does the commend 
sources
say?
How long has chrony been running?
Why are you doing systohc?
