Actually, as of October, 2007, System z's Server Time Protocol (STP) can act as a Simple Network Time Protocol (SNTP)/NTP client in order to receive its master time. Your System z9 (or z10) is capable of that function if you get the STP option. You can visit here to start getting some more information:
http://www.ibm.com/systems/z/advantages/pso/stp/ntp.html Also, I agree that it is highly desirable to have your mainframe act as the master (S)NTP server for your other servers and even PC/Mac clients. Let the mainframe be the highly available "time boss" if at all possible. See here for some setup information (for z/OS): http://publib.boulder.ibm.com/infocenter/zos/v1r9/index.jsp?topic=/com.ibm.zos.r9.halu101/sntpdinfo.htm So, in summary, you can use the STP feature to let the mainframe get a master time for your organization (via SNTP/NTP client support, such as by connecting to a dedicated GPS box that delivers its time signal via a closed NTP link). Then use the mainframe's SNTPD -- included with z/OS -- to keep every other server and client in sync. That'd be the preferred approach. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z Based in Tokyo, Serving IBM Japan and IBM Asia-Pacific E-Mail: [EMAIL PROTECTED] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
