the RK3399-Q7 contain a real-time clock (RTC) on-module. The RTC is read by the kernel on bootup and used to set the
system clock.
To check the RTC value, use
hwclock
:
hwclock
Thu 30 Apr 2015 03 : 51 : 20 PM CEST - 0.826662 seconds
The RTC will be set automatically to the system clock on shutdown, so you can set the system clock using the date command
and reboot to update the RTC:
date -- set 2015 - 04 - 20
date -- set 03 : 51 : 30
You can also update the RTC immediately, again with
hwclock
:
hwclock - v
You can set up an NTP client so the time will always be updated from the Internet. Install the client first:
apt - get install ntp
Feel free to change the
/etc/ntp.conf
file to use more local time sources (change servers from
pool.ntp.org
to use a
server from your country, such as
at.pool.ntp.org
).
