Incorrect system time

[Jone]

Hi all! I got confused with this:
Xfce panel clock show the right time, in my config.scm:
...
(operating-system
...
  (timezone "Europe/Moscow")
...

but:

sudo hwclock --localtime
2018-05-09 19:53:59.559850+0300    (Ok)
sudo hwclock --utc
2018-05-09 22:54:06.184854+0300    (wrong!)

and time in system logs too are incorrect.

In short, I need set system date/time for "Europe/Moscow",
everywhere.
