MikroTik

I have RB433AH ROS 3.13. I set the clock to the right date and time, after restart the date it Jan/01/1970, the clock is 00:00:00. Only the time zone is right?
Any suggestions what to do?

Have you configured the NTP client properly?

There is no realtime clock chip with battery on Routerboards. So every time the RB is rebooted, it loses the time. You must add settings for the RB to get it's time from a NTP time server using the NTP Client.
