I can also verify this as I just setup a brand new rPi yesterday. Downloaded a fresh copy of jessie, booted up the rPi, did the setup for it, made sure all apps were up to date (with 'sudo apt-get update ; sudo apt-get upgrade' then installed MM as per the wiki’s instructions. Done.
By the way, while inconvenient every time, you can issue a 'pm2 restart <MM>' (where <MM> is whatever you called your process) to refresh the display and those times would display properly again.
Regarding the ‘keyboard and mouse’ part in your post … I use a wireless set. So the rPi is mounted behind the monitor and only has 2 wires on it: power and HDMI. There’s a USB dongle plugged in that’s for the keyboard and mouse which I rarely use. Specially since I log in remotely. The only time I need the mouse or keyboard is if something bad happened and the rPi won’t boot up normally. But other than that, not needed.
