As part of the PCI audit we need to look into adopting NTP
(network time
protocol) on the mainframe to ensure all of our 'systems' are
synchronized. Can STP provide NTP client capability to maintain 'same
time' across heterogeneous platforms.
z/OS cannot be an NTP client. However, you can use STP (which is not
NTP!) to maintain the clock on the z and then use z/OS as your NTP
server for the rest of your systems.
o AFAIK, there is no way to maintain accurate time on z without
spending the big bucks for STP (or ETR, if it's still supported).
o With STP, z will probably have the most accurate time of any
system in your shop. Logically, z should be the NTP server.
o But, as so often stated in this list, logic must sometimes
yield to Legacy inertia. And in the OP's case, it appears
that "Legacy" is the existing non-z NTP server. IBM would
be well advised to learn to play well with others as an NTP
client.
