Correct. Will not ever happen. Big can of worms. > I could run phc2sys on these hosts and then sleep against > CLOCK_MONOTONIC.

If you really can't/won't use phc2sys, then you can also do clock_gettime(CLOCK_MONOTONIC, t1); clock_gettime(phc, t2); clock_gettime(CLOCK_MONOTONIC, t3); and calculate offset = ((t3 - t1) / 2) - t2 every once in a while, then use linear interpolation to convert deadlines from the PHC time scale into monotonic deadlines.
