I cant edit the time, when i try to edit it the calculator crashes.
Did you update your Ndless to a revision greater than the one indicated in the README ?
BTW, here is a message for everybody : nClock has some problems with daytime conversions, I'm aware of it but sadly have no time to solve it.
Basically there are three conversions, one is accurate (timestamp to day) but the two others are not (guessing weekday and day to timestamp) due to a float approximation : this is why you may enter two more days when configuring the time and may have a wrong weekday. Sorry about that..
