I use RUT955 with RUT9XX_R_00.06.07.1. I configure the RUT with the UCI import method.
I got same issue with previous firmware.
I use a time server defined in Services >> Time Servers.
After I configured the RUT, date and hour are wrong. If I delete the time server and then I add it again, date and hour become good.
I think there is a bug with time server when using UCI import.
