Time Wrong on Home Screen

Here is an interesting problem. The time on my Home Screen is 2-3 minutes, yes minutes, off. The time shown is earlier than the actual time. The Z11 has an ethernet connection to the network. I don't have an NTP server running on my network and every other device shows the correct time (router, NAS, TV). I did try starting the NTP server on my router and setting it to intercept NTP calls. I then restarted the Z11 and the time was still 3 minutes slow. It seems like clock drift, but the Z11 is set to use the time from the network so clock drift seems impossible. Does anyone have any ideas on where to look or what to try? I've restarted everything a few times now.

This is after yesterdays big update. I am not sure if it was like this before or not, I just happened to notice it. I am assuming that this will affect recording shows.

I fixed it (for now?) by going to Settings - Network - IP Settings and selecting DHCP again. It was already selected but seems to reset something. I am still curious as to why.
