In the interests of full disclosure, with the latest service, z/VM's support for STP is limited to a) Obtaining the timezone from STP b) Timestamping I/O with the Correct Time (for XRC) So while STP will ensure that the LPAR has the Correct Time when the LPAR is activated, and the TOD will be steered to the Correct Time, any of the Large Time Jumps induced by the external time reference will be ignored by CP, except for I/O timestamping.
