Here is how it works:
1. sys-net runs some standard clock synchronization service (ntpd,
systemd-timesyncd - depending on template); it is enabled by setting
'clocksync' service (qvm-service tool in dom0).
2. Then every VM, including dom0, synchronize its time directly from
there. In case of VMs, it is done by qvm-sync-clock (called from
qubes-time-sync.service in the VM), controlled by two things:
- absence (or disabling) of 'clocksync' service (qvm-service)
- qrexec policy, where actual VM used for time sync is set
(/etc/qubes-rpc/policy/qubes.GetDate)
For dom0, also qvm-sync-clock is used (slightly different one for dom0),
and the VM is set by 'clockvm' global setting (qubes-prefs).
In theory, all those places should synchronize UTC time, and honour
local timezone for display purposes. But maybe somewhere it is messed
up... I'd start with checking timezone in sys-net and time
synchronization with the network (systemd-timesyncd.service) there.

Q: Why is top-posting such a bad thing?
