QUBES 4 r4 - dom0 UTC time is incorrect - manual change each reboot. QUBE-A-LICIOUS 13/02/18 13:51
Hi there,

I have a fresh install of Qubes 4r4.  However, when I reboot and or login I have to manually change dom0 time to UTC.

Impact: Whonix/Tor does not work because of the incorrect time.

Manual workaround:
1.  Get the correct UTC from a browser.
2.  Open Dom0 Terminal and update to UTC such as the following:
       
      sudo date --set "2018-02-13 21:30"

3. Shutdown Service:sys-whonix
4.  Restart a whonix domain such as Domain:anon-whonix(this restarts the sys-whonix service that was just shutdown.
5.  Then run WhonixCheck to make sure it works.  It usually does and Whonix/Tor is functional.

=================
Qubes cannot be this bad, really.

How can I have this Date and time correctly updated on boot up?  Like it should.

Thanks for all your help.

Most times it is easy to point on another guilty one instead looking what may happen with the own stuff. So far you are the only one with this misbehavior.
Qubes works as expected - at least in this point.
But most user already experienced this behavior; qubes-os or any other distribution.
The keyword is hwclock. You always update the software-based time, but if you restart, all temporary data is gone. (should)
So your OS fetches at boot the time from the bios.
If you update your time within the qubes-os, you should update your hardware clock (hc) as well: sudo hwclock --systohc
If your time resets when you unplug your device from power supply, your device's battery is flat.

Try adding the following flags to date: -s -u

Best,

----------------------------------
I did some analysis this morning.  So at the same point in time the following settings on my Qubes laptop showed the following values.  (Bottom line is that whonix/tor does not work)

1.  The hardware BIOS clock is:  1030  (BIOS battery good, removed laptop battery for few hours and date/time stayed same)

2.  Dom0 time is: 0530 ( via date command)

3.  service:sys-whonix is:  1030 (via date command)

4.  Clock on upper right of screen is:  0430

Tor Boostrap info is:

Whonixcheck gave up waiting
clock skew -21635 in directory from DIRSERV

sudo date --set “2018 -02-18 17:30:00”

-----------------------------
I think that on a normal bootup the clocks should be in sync and Whonix/Tor should work.

bios time differs a lot from dom0 and dom0 time seems in the UTC (timezone), while the clock on your desktop should be therefore in the -1 hour timezone.
There is already something wrong, isn't it?
Could you please set the correct time in dom0 and do a 'sudo hwclock --systohw' to get dom0's sys date and bios time in sync.
And reboot pls. After reboot check the time in bios, dom0 and your clockVM (probably sys-net) before connecting to any network.
In System Tools -> Qubes Global Settings in dom0 you can check the name of the clock VM.
The time of your whonix should, as far as I know, differs in timezone as qubes built-in rule randomly each bootup of the VM. (Do not know for sure)

I either do not know whether sys-whonix only changes the timezone and if it is an attack surface if someone from the outside could simulate/fake specific minutes and seconds your network-time-daemon adapt and your whonix could be associated to your isp.

Even there seems to be some misconfiguration I never got, the behavior remembers me to an empty hardware battery.

==============
1.  I changed to the correct Time Zone from the command line.  Fixed the -1 hour offset.
2.  I updated the dom0 time
3.  I ran the sudo hwclock -w to set the hardware clock from the current system time.
4.  I rebooted the laptop.

The current results are:

1.  BIOS clock is:  1530  (via BIOS menu on startup)

2.  Dom0 time is: 0930 with correct time zone.  (Correct!)

3.  service:sys-whonix is:  1530 UTC

4.  Clock on upper right of screen is:  0930 (Correct!)

5.  sys-net is 0930.  (Correct!)

6.  Tor Boostrap info is:  (from sys-whonix occurs right after startup)

ERROR systemd clock check result:
Unexpected results by timedatectl
local time:  15:30:00
universal time: 15:30:00

However….
7.  Tor browser works!!!

I think that I am close, this error should not be coming up.  Any ideas?

Could you check sys-net has the qubes service clocksync set?

Hi, in my case, one day when I turned on the computer, the clock on the panel started showing CST (=UTC+8). BIOS and Whonix showed UTC, which I wanted. When I checked the time at dom0, times were totally correct but as I said somehow CST time was displayed on the panel clock. Temporarily I made the time incorrect by using -s -utc so that the time I wanted was displayed on the panel. I plan to download clock apps instead of the default one on the panel but anyone has any idea on this? Thank you.
