Thomas Guillemard 97d0c62423 Accurately implement steady & system clocks (#732)
* Improve SteadyClock implementation accuracy

* Rewrite system clocks to be accurate

* Implement IStaticService 100 & 101

* Add time:* permissions

* Address comments

* Realign TimePermissions definitions

* Address gdk's comments

* Fix after rebase
