Qubes OS version:

R4.0-rc2

Affected TemplateVMs:

sys-net on fedora-25

General notes:

After installing Qubes, sys-net never synchronized time with the internet's NTP servers. > 24h have passed since the instalation, with countless reboots and the clock was still skewed.
ntpdate wasn't installed on sys-net, I had to manually install it and synchronize via ntpdate 0.pl.pool.ntp.org.
This is not a problem with qvm-sync-clock, this is a problem specifically with sys-net's automatic NTP synchronization.

Can someone reproduce the problem, or is it just a problem with my installation? If not, I'll check it on a secondary computer with a fresh installation in about 2 weeks or so.

I can reproduce this error and the fix. The bug is pretty annoying because after installation the clock is wrong and even if you set it via sudo date -s in the dom0 it's will still reset clock to some random time, after a few minutes.

Actually, there was chronyd.service running instead. In 4.0rc4 templates, it is no longer the case and systemd-timesyncd.service is running properly. And apparently it deals better with time sync, across suspends.
Can someone with 4.0rc3 updated installation check logs of chronyd.service?

But there is still other problem - VMs do not synchronize clock with. Apparently qubes-sync-time.timer is not started.

@marmarek
Do not sync VM time with clockvm if it's set to network time sync 
When VM is set to synchronize the time with the network, to not sync its
time with clockvm.
Besides not having sense, in default configuration it will lead to
loopback qrexec connection (sys-net -> sys-net), which will hang.
