Recently disconnected my nero 3 and same issue started with the time thing being wrong. Going into settings and refreshing would fix but doing this daily was not optimal. After reading this forum thread I went in and deleted the nero. After doing so I then began getting update notifications from the light. It was like the nero was blocking anything from reaching the Ai so it was defaulting back to what I would guess was a factory setting. If this doesn't fix the date thing I will post more, but if there are no more posts the removal of the nero 3 has solved the issue like it has for others. The sole reason for this post was the added info that the light was not getting updates while the nero 3 was disconnected but not deleted from the tank.
