a) I can see the time in the top panel.
b) Clicking and choosing Time & Date Settings reveals correct Location.
Set the time: O Automatically
--this simply shows the wrong time (about 6 hours behind)
Set the time: O Manually
--I can change the time, but it does not stick: it ignores me.
This is too annoying as I depend on file dates and times which are now nonsense.
Profuse thanks for any help.
