This is not working on a new mSD with only chrony installed and the changes listed below.
It works on F22 'out of the box' with these changes.
From the Fedora-arm list:

In RHEL7 is currently chrony-1.29 which doesn't have the no RTC fallback with the -s option. You might want to wait for 7.2, which likely will have chrony-2.1.1.

Got to get this working...
So can we have chrony-2.1.1 ??? Please :)

On the Fedora-arm list I learned that chronyd and systemd-timesyncd conflict. F22 is using chronyd with systemd-timesyncd not enabled. To get chronyd to set the system time based on the last boot you need:
In /etc/sysconfig/chronyd OPTIONS="-s"
and /etc/chrony.conf #rtcsync rtcdevice /dev/nonexist
shortly after boot if no network connection, your system time is set to the last content in /var/lib/chrony/drift
So please add chronyd to the minimal install and set it with these 'defaults', or provide an easy way to configure for 'no rtc'.

The archlinux wiki says this should work at boot even without a network connection but it is not. Perhaps there is some extra steps to set this up right?
If not, is this a bug? Not supprising that the Intel based testing did not see this, as how many Intel boxes do not have an rtc? Only those with dead batteries...

I just did a test, as timedatectl indicates that ntp is on. It did not set the time on reboot. It is not doing that auto stuff mentioned in the description. :(

Oh, I should have read further down the page of: https://wiki.archlinux.org/index.php/Systemd-timesyncd

Again, this requires the network to be up?
I use timedatectl to set my timezone, will look more into it. Could be all is rolled together...
