Oh, I'm sure you are not going to be interested in my implementation.
First of all, it uses NTPv3. However, no, I don't care about
authenticated data.
And since RSX don't have anything equivalent of adjtime(), all I can do
is do hard changes, so I only adjust if the delta is becoming too big
(which in my case is lots of seconds). And since I have such lousy
requirements on precision, I also do not try to actually get a very
accurate time to start with. So it simply drags a timestamp out of an
NTP server, and then I set the time based on that.
It's very simple. But it's good enough for the things I want it for. :-)
It's about 200 lines of C in total. And that is with all the twiddling
of RSX.
