You need at least three time sources, the more the better. The time sources you have, what stratum are they at (stratum = how far from a time source which they are.) Verify that your organization's time sources is independent of each other (a lot of people fails at that...) Can the CPC be a time source for other system ie can it be a server in ntp parlance ? Can the CPC be added as a peer ? Would it be feasible to run the z13s as time servers in a peering agreement which each other ? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
