Hi -
I'm certainly a member of the OFWFMA, but my Zumo won't do that.
On the right hand side you can have four little windows and they, as Tracus says, are selected by poking at the window in the trip computer screen that has the data you want. The unit seems to remember what data you want to have when you are in non-route-following mode and what data you want when you are following a route.
Tracus says you get two windows, and he is correct. However, if you go to Tool>Settings>Map>Map Data Layout and select More Data View, you can have four little windows.
When I'm not routing, my selections are Total Time, Odometer, Elevation, and Speed.
When I am routing they are Elevation, Via Arival Time, Via Distance, and Speed.
As to the clock that shows on the map screen, I cannot change it. The clock on the main screen can be changed to 12hr, 24hr, and UTC.
Tom
