Is z/OS the server or client? I can't really tell from your question. If server, then the time served should be taken from the z/OS system clock. But since z/OS does not come with a standard NTP server, I don't know what the source actually it. If it were me, I'd use the z/OS C "gettimeofday()" function. Which I would _guess_ uses the TIME macro or maybe the STCK[E] instruction.
I am not aware of any NTP client for z/OS either. So I don't know what it would do. I am _certain_ that the only way to _safely_ change the TOD clock is via the new STP or old ETR hardware. Those sync to an STP or NTP server. Howerver, however it is done, it would pretty much need to be an "all or nothing" type of affair.
