Oh, sorry, my fault. I was under the impression that Michal created
the API especially for this purpose, but looking at the code it's not
done automatically.
At one point, I seem to recall a proposal of adding an <on_resume> tag
to domain xml that could explicitly request time resync each time the
domain is resumed; but I don't know if anyone implemented it yet.
