RE: [AS400] Syncing time on the as/400

["Kahn, David [JNJFR]" <DKahn1@xxxxxxxxxxxxx>]

Well of course I can't look at Ed's link till the weekend (have I mentioned
that before?) so I'm guessing, but it might be similar to something that was
suggested by someone (Bob Cozzi?) when this subject came up a few months
ago. He speculated about hooking up a relatively cheap clock synced by radio
to an atomic clock. These are readily available. Another possibility, if you
want to avoid the Internet, might be to use a GPS receiver. These are now
quite inexpensive and generally come complete with a data port for feeding
loggers and other instruments. The accuracy of GPS depends on precise
timing, and GPS receivers sync themselves to the atomic clocks carried on
board the satellites. The accuracy, particularly with DGPS ought to be
within a few nanoseconds.

Just a thought.

The answer to your question is at the following page;

It has devices for syncing up your AS/400, unix, NT, Novell, HP, and DECs
devices to atomic clock accuracy better than 100 microseconds.
