Timestamping of write operations is an essential mechanism that XRC uses to maintain sequence consistency of write operations to the secondary volumes. When the XRC system data mover is run on a remote recovery system that does not share a common time reference with the application systems, it is important to configure the system in a way that avoids the introduction of incorrect timestamps into the XRC storage control sessions. To do this, you should use SuppressTimestamp(YES) in parmlib member ANTXIN00. For more information, refer to ANTXIN00 parmlib parameters..
