Since it's clock-change time, I figured I'd check out some of the ntp
clients I don't use. Two of them (nistime.exe and ntp.exe) didn't work
properly here:

1. nistime hangs when I run it. The following lines:

nistime -m0 -s0
nistime -m2 -s0

both "hang" in an OS/2 window. Anybody have any suggestions?

2. ntp (ntp107) doesn't check the TZ environment variable. It set my
date to GMT time _and_ didn't set the date ahead; thus instead of moving
me ahead 8 hours it moved me backwards 16 hours. I used this line:

ntp tick.usno.navy.mil

ntp changed something else too and I can't get my time to set properly;
I'll reboot after I send this message and see if that fixes whatever the
problem is.

And the other four that I know of:

3. time868 (time868f) is a PM program with "a bunch of options". Seems
to work okay.

4. daytime works quite nicely. The following line:

daytime tick.usno.navy.mil

set my clock and took the TZ environment variable into account.

5. I didn't try TimeKeeper/2 (timekeep) because it doesn't appear to
offer any functionality that the others don't have _and_ it's shareware.

6. os2ntp is what I usually run, and it's still the most accurate. It
uses a phase locked loop and samples as many time servers as you want,
which gives extremely high accuracy once it's synchronized. The problem
with it (and the reason I'm testing the other ntp clients) is that it
automatically adjusts for Daylight Saving time _but_ the phase locked
loop takes a while to settle down when it's suddenly hit with a 1-hour
error (undamped oscillations result).
