Subject: Preliminary support for realtime clock (#2772)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Initial support for realtime clock.

* Add realtime-clock render feature where seems appropriate.

* Fixes to make NVAPI compile properly.
Change realtime-clock.slang check to use maths that can't overflow.
