Sorry if there's a thread for this already; I couldn't find one.
My Nook STR won't keep the correct time. It's always 3 minutes behind or 3 minutes ahead of the correct time. The weird thing is, it changes every time I connect to wifi.
If the correct time is 6:00, for example, my Nook will say 5:57. If I then connect to the wifi, it will say 6:03. Turn off the wifi and turn it back on, now it's back to 5:57. Disconnect and connect again and it's back to 6:03. Continue ad infinitum.
