Hi,
I have a bit of a strange problem here. On my RaspPi2 I have a persistent problem with the date slipping. When I boot up the date and time is correct, but after a short time (30 secs or so), it slips to some random date in the future. This started happening when I was running the stable last build of Krypton, so I decided to try updating to the latest beta Leia 8.90.006 to see if it went away. It did not.
I originally had no NTP servers set, but I tried the standard pool, a pool for the UK and a pool for IE. None of them work. I tried setting wait for network - but this made no difference.
I noticed this on dmesg, which look as if it might be the root cause:
