[Elecraft] Mac Clock Question

[Bayard Coolidge, N1HO]

 I run my iMac 24x7, and do have it configured to use the ntp.org pool servers, and it appearsto do the trick for the various WSJT-X modes that I use on HF. However, even when I doreboot occasionally, any transient loss of sync to the NTP servers doesn't seriously affectme when I use WSJT-X. OTOH, since I spend a lot more time listening than transmitting,while searching for "new ones", NTP has plenty of time to sync back up :-)
I suppose if you want to really go overboard, you could get yourself a GPSDO and theninstall gpsd (GPSd — Put your GPS on the net!) and NTPsec (Welcome to NTPsec)and then you'd not only be good-to-go for the WSJT-X modes, but you could then serveup a reference for the rest of us. Both of those can, AFAICT, be built for Windows,Linux and macOS, assuming you have the software development tools (compiler,linker, libraries, etc.) installed.
BTW, NTPsec is a new/rewritten implementation of NTP that is far more secure and robust,and does not need gpsd or a GPSDO to use. If you're concerned that your currentOS/computing environment might not be behaving as well as you'd like with respect to NTP,it might be worthwhile to take a look at NTPsec.
