FWIW, I believe most hospitals are more than capable of looking after equipment with complex maintenance schedules. They have endoscopes, blood gas analysers, gamma cameras, MRI machines, dialysis machines and a rake of other stuff that has a schedule requiring attention more regurally than once every 6 months. I am not sure how much un-networked equipment that requires UTC to 1 second and doesn't already have a suitable maintenance schedule exists in hospitals. David.
