I was part of a conversation here about turning WDR on and off like a day/night schedule. I am sure you have the sun washout like most of us during the day. I did call LaView and Nelly's with the same question to see if they will have an option for us in the future, unfortunately they could not say and were no help. You might try playing with WDR and seeing if you can find a middle ground.
As far as the moving of the time stamp, you are correct, as far as I can remember in reading this whole forum/thread I don't believe anyone has been able to move it, only turn it on/off.
It would be nice if all the grayed out options were available, even though this Doorbell is far from perfect we still have a huge amount of more control over it than the other cloud only Doorbells out there.
