All computers are intrinsically inaccurate. According to a bit in NewsWire,
aging hardware and IPLs, etc., contribute to this situation on the AS/400.

This is why we've been looking for some way to coordinate with an external
standard. The best thing I've heard of so far is NTP, or Network Time
Protocol, a TCP/IP application that relies on a network of time servers.
The same article in NewsWire (by Mel Beckman) mentioned that there is a
PRPQ that provides an SNTP (Simple NTP) client for the 400, which would set
the date/time clock each time it's run. So far Support Line says they can't
find it. Anyone know anything about this?

BTW, I've put such a client on my 95 machine. It runs every time I restart,
but could be put on a schedule. It has been making adjustments of a few
seconds every time.
