System time in taskbar doesn't change after corrections

Following by these articles: Time, Linux tips i tried to set time in my Arch GNU/Linux. Each time after all actions i get proper time from timedatectl, but time in taskbar doesn't change. After reboot i get wrong time from timedatectl again.

What should i do?

p.s. I use Arch with Virtualbox if it is important.

Could you please specify what actions exactly you are taking? The commands you run, for example.
And after rebooting, how exactly is the time wrong? Is it just the wrong timezone, or is the clock completely off?

Sure.
1)After turning on my VM, i type timedatectl and
get:

$ timedatectl

Current local time is 09:22. Current UTC from here is 06:26.

2)$ sudo timedatectl set-time "2015-05-06 09:28:15"

timedatectl

So, what i get after reboot:

$ timedatectl
Local time: Wed 2015-05-06 14:08:41 MSK
Universal time: Wed 2015-05-06 11:08:41 UTC

NTP enabled: no
NTP synchronized: no
RTC in local TZ: yes
DST active: n/a

Timezone is always right.

So you're in UTC+3, but the (virtual) system is giving you some bogus time (approx. 4h 10min ahead).
Is the time and timezone on your host system (presumably Windows) configured properly?

I'm not running any Linux system on a clock configured for localtime, so I can't quite tell (nor test) if the RTC's behaviour you show is normal...
However, I just stumbled over this: https://www.virtualbox.org/ticket/1310.
Could it be that your VirtualBox is running with localtime? And if yes, what happens if you make it use UTC?

no, my host system time is wrong since i tried to install Kubuntu in Virtual Box(about 1.5 years ago)

Default settings of my VirtualBox include checked "hardware clock in UTC time" parameter. Should i change it?

So... have you tried adjusting the host system's time (and your physical machine's clock)? If your host's time settings are off, I don't expect the VM to behave correctly (but I could also be wrong).

No, I would leave it in UTC. I'd also

timedatectl set-local-rtc 0

just to rule out localtime-related issues.
