Comment 20 for bug 1589780

Note: while the wrapper approach would work (after some test and polishing), compared to the upstream -X it will have one drawback.

If future containers grow time-namespacing as a feature it will still default to not adjusting the time in containers.
But as long as we don't know how time-namespaces will be implemented we can't code special cases for that (while chrony itself can try and fallback which is the -X option).
