I was also thinking (while working on an unrelated patch) we could use a system call like
int clock_getoffset(clockid_t clkid, struct timespec *offs); that returns the current offset between CLOCK_REALTIME and the requested timebase. It is of course racy, but so is every use of CLOCK_REALTIME. We could also use a reference other than CLOCK_REALTIME that might be more stable, but passing two arbitrary clocks as input would make this much more complex to implement.
