Dennis, I do not know about timestamps but all our Production dasd z/OS - z/VM - and LINUX is mirrored to an undisclosed location using HUR.

Technically, I'm pretty sure a Linux timestamp looks just like a z/OS timestamp. Mabye they mean they don't support it because they haven't tested it. We run GDPS/XRC which relies on the timestamps. A separate z/os data mover for VM is required with the mixing of the stamped and non-stamped at the moment. If you need timestamped VM I/O, best to call IBM and ask.

I know that there are challenges because z/VM doesn't timestamp its I/O but Linux does. I'm being told that HUR doesn't support Linux timestamps. Is that true? Allegedly, this lack of support means that a z/VM replication environment would need to be separate from our z/OS replication environment, including a separate z/OS LPAR to control the replication.
