Wrong time device

Hi, I have a problem regarding the time that arrives at the application server, some devices send the date correctly except for some frames which are dated for example in the year 1980 or in 2043. I have verified that both the correct and incorrect frames are were taken from the same gateway. Anyone have any idea what the problem could be? Thank you

I would verify correct time and/or GPS lock (if present) on the gateway. It looks like uplinks are carrying a bogus time, but the log entries are using the correct time from the LNS. At first glance without more info, anyway.

Thanks for the reply, I’ll look into the gateway further

Did you find a fix? I have the same issue, but in my case the year is 1999.
