Yahbut, and this is as I understood it to be, and whatever. It still does not address the primary criticism we get from the squatty box people. That is:
IT STILL REQUIRES AN !OUTRAGOEUSLY! !EXPENSIVE! SERVICE, ETC TO GET THE TIME INTO THE z/BOX!!! Which by the way is totally free for any other platform I know about.

Hal, Sorry for the delay in posting this. I have been on vacation since Dec 19th and was not aware of this posting. I work in the System z Hardware brand organization, have been a member of the STP team for the past many years and have worked closely with the development team to bring STP to market. It seems there have been a lot of postings in the past 2.5 weeks and there is a lot of confusion and incorrect information in some of the postings. But let me attempt to respond to your orginal posting. Server Time Protocol (STP) is a server-wide facility that is implemented in the Licensed Internal Code (LIC) of the z10 EC, z10 BC, z9 EC, z9 BC, z990, and z890 servers. STP presents a single view of time to Processor Resource/Systems Manager(tm) (PR/SM(tm)), and is designed to provide the capability for multiple STP configured servers to maintain time synchronization with each other. Besides providing the capability to synchronize multiple servers, STP also provides NTP client support. NTP client support addresses the requirements of customers who need to provide the same accurate time across heterogeneous platforms in an enterprise. If I understand your requirement that is what you want to do. All STP functions are enabled only after feature code 1021 is installed on the server. Thi includes the NTP client support mentioned above. Many customers have already implemented STP on a single server so that they can provide the same accurate time across heterogeneous platforms. Once STP is enabled on a server, you still need to configure it - described in the Redbooks - assign CTN ID, assign roles such as Preferred Time Server and Current Time Server. On a single server you have the choice of running z/OS with its CLOCKxx member coded to run with STPMODE YES, STPMODE NO or with SIMETRID. If STPMODE YES is coded in parmlib, z/OS will respond to STP interrupts and machine checks. To understand better the implications for operating systems that do not support STP please refer to http://www- 03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/FLASH10631 I hope this helps. At this time I will not attempt to clarify some of the confusion in other postings until I see responses to this one.
