Thanks for looking!
Actually, CLOCK_MONOTONIC_RAW on MacOS was exactly a problem: this clocks have nothing to do with astronomic clock. And
wemust put real UTC time into UUID. 
I’d be happy to reuse instr_time.h infrastructure, but it just does not fit for the purpose. It’s optimized to measure
timespans.
