The Time Namespace ability to provide per-namespace offsets to the system monotonic and boot-time clocks is driven by container use-cases as explained in that article.
This ability to have clock offsets on a per-container/namespace basis will help in the restoration of containers on the same or across systems and surely other possible use-cases to come about as well.
This support already landed in 5.6 Git as part of the timers/core changes.
