Jetson AGX Xavier date

Hello ,
I recently bought a new Jetson AGX Xavier and I received it today , I have started the Jetson and changed the date and time , but when I powered it off and started it again ,it didn’t save them and they restarted to 28/01/2018 17:00.

I want to know how to fix that.

Hello @mr.youcef.b

The Jetson AGX Xavier has super capacitor(C512) which works as RTC. If Jetson AGX Xavier has not been energized for a long time, capacitor may totally discharged. Have you observed this situation several times?
