Bug#448871: Should give us the option of syncing time

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.
