It's not a matter of intelligence. As I said, changing the time in VM is simple enough. The guests are the issue. VM allows all sorts of systems as guests, CMS, GCS, MVS, z/OS, TPF, LINUX, VSE, etc. etc. I can see no way that VM can enforce a guest to handle this in any certain way. It will always be up to the guest to control its own reactions.
