I can see several possibilities. In order of preference:
1. Using NTP to set the TOD forward by a small amount.
2. Using NTP to set a vir

The "problem" is that z/OS _cannot_ allow the TOD clock (hardware clock) to
go "backwards". The way that STP addresses this is that the STP software
can "speed up" or "slow down" the TOD increment pulse (or whatever it's
called). This is the hardware portion of STP. And I think that hardware

Hi,
Someone is using a NTP Server and System z for PCI-DSS compliance regarding to
time synchronization.
I s a must to use a NTP server for PCI-DSS compliance?
