The virgin whonix templates downloaded with official Qubes R4 rc4 release,
did not result in errors via whonixcheck. However, subsequently after updating the
whonix-gw template I get the following system time error:
ERROR: Systemd Clock Check Result:
Unexpected results by timedatectl.
Local time: Wed 2018-02-14 10:25:33 UTC
Universal time: Wed 2018-02-14 10:25:33 UTC
RTC time: n/a
Time zone: Etc/UTC (UTC, +0000)
NTP enabled: yes
NTP synchronized: no
RTC in local TZ: no
DST active: n/a
It is generally recommended to keep the default as per Whonix Design.
 If you did not change timezone related settings, please report this
Whonix bug. If you know what you are doing and changed this on purpose,
feel free to disable this check. 
 Create a file /etc/whonix.d/50_whonixcheck_user and add:
whonixcheck_skip_functions+=" check_systemd_clock "
In reality, there’s approx 2 minutes dfference between my local clock and the whonix system clock
