Not really - when I finished `clock_settime` a couple of months ago for Linux, I decided to also do this one for sake of completeness. At the time I started working on this issue, I wasn't sure that the clock is immutable - in NVPTX ISA it only says "this is special register", but not that it is not mutable. 

Only learned about it yesterday, when I finally got time to work on this PR, during compilation of some NVPTX assembly to see if it would actually work.
