Hi,

I had a search through the tech@ mailing list and a grep through (git) 
commits but did not find anything about the topic.

Working on getting OpenBSD support into Chrony, it does use 
clock_settime() for setting time (and adjfreq()).

The helper running as root which does the calls to privileged tasks like 
opening a socket for a port <1024 and setting time, uses 
clock_settime(). Since that call is not pledged, pledging this helper is 
not possible right now.

I was wondering if there is specific reason that clock_gettime(), 
adjtime() and adjfreq() are covered but not clock_settime()?
