We're planning to move to STP-based (Server Time Protocol) time management solutions.
The Server Time Protocol feature is designed to provide the capability for multiple servers and Coupling Facilities to maintain time synchronization with each other, without requiring a Sysplex Timer. The servers and Coupling Facilities that are capable of supporting Server Time Protocol are the z890, z990, and later servers.
Are there any known issues with STP, particularly in regard to daylight saving changes?
CA PDSMAN has no known issues with Server Time Protocol or Daylight Savings Time.
