>how long to walk to and return from Monchhutte<
Depending on your fitness level and ability to deal with high altitude it will take anywhere from 1.5 to 3 hours roundtrip. You will want to spend at least 30 minutes once out there to have a hot drink and take in the views. I assume you know it is a walk across a snowfield atop a permanent glacier? You will need good hiking shoes.
>It looks like the maximum stay for the day is under 4 hours at the top, between the station and the hut<
You can stay up top as long as you want, just don't miss the last train down!
