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.
