Every time I start my odroid XU4, the date seems to be 11th Feb 2016 for some reason. timedatectl command shows the below result:
Network time on: yes
NTP synchronized: yes
RTC in local TZ: no1 Answer
If you don't have the RTC backup battery, the system will not preserve the time. You can purchase one here: rtc-battery.
However, the time should be kept if you maintain the ODROID XU4 connected to the power supply. If this does not work, I could think this is a hardware fault. Other thing you could try, is using an external RTC module, or run an script in every reboot to sync the clock using Internet for example.
