Don't know.. I saw this on the web
Centos 7 use systemd. I suggest you use it.
Use the command timedatectl
Enable network time synchronization:
timedatectl set-ntp True
Create a conf file:
vi /etc/systemd/timesyncd.conf
with content like this:
[Time]
NTP= yourserver.org
Start systemd-timedated service:
systemctl start systemd-timedated

it :-)
Can't find it in the repo, what provides it?

Hello
I don't think any armv7 board like cubie has a battery to
backup clock
I think ntpd is the only way, and seems to work well on my
bpi with c7. I will check if dns resolution works when
date is 1970.
I think setting the currenttime can be a good idea on the
rbf tool :-)
On the Fedora-arm list I was pointed to Systemd-timesyncd
This does MOST of what I want. All that I think needs to be
added is for it to be enabled in the image and a initial
date/time of the image built date be there so the firstboot
has a decent time.

How is system time set at boot?
Is ntpdate run after the network is
ready? How long does it retry waiting for the network
to be available?
I have seen a number of challenges becuase the system
time is back at
the epoch start as there is no battery rtc. And I
wonder how many
armv7 boards have a battery to maintain time across
boots?
Minimally, a process could right the time, in the proper
format, to a
file, say /etc/currenttime every 5 min and at shutdown.
Then date can be run early in the boot process, piping
this file in. It
would not be perfect and does not help, much for new
installs, but
better than epoch start.
Plus /etc/currenttime can be at least set to the image
build date/time
so not even firstboot will be at epoch start.
Opinions?
