rdate, as used by the installer, uses SNTP.
Ahhhh... (again) This was added fairly recently. Interesting.
The point remains. The uncertainty in the time from the server is
proportional (or worse) to the network delay.
Not with SNTP it isn't, AFAIK.
Looking at the source code, the SNTP implementation for the modern
rdate is more or less exactly as I described it in my original post.
The uncertainty in the timestamp value is exactly proportional to the
round-trip time.

This has gotten pretty far afield of the original bug-report.
I've learned some things, and that's good. Thank you, Joey, for
forcing me to take a look at the source code -- always a useful
exercise!
But I'll stop now, as it's no longer contributing to fixing the bug
in the original report.
