12am/pm is driving me nuts. It would be great if Newton calendar on Android would follow the system time settings.
This is interesting, as I see 24h times in my Newton Calendar.
You are right. This was a bug, although it seems a minor one and maybe not even in Newton, who knows. For me, resetting system time to am/pm and then back to 24h gave me 24h in Newton.
So this item can be closed as far as I am concerned.
