The fact that the developers have made no provision for a well known 
problem is simple incompetence, and I would not be surprised if they 
were found liable if anybody was killed. Yes the software needs testing, 
but the simple operational requirements should not need to be explicitly 
specified in the specifications? ANYBODY designing a system that has 
essentially to work 24/7 and perhaps as a patient is being transferred 
across timezones should not be an area where they simply don't bother 
about using a stable timing system? But then if they are using windows 
anyway perhaps they don't even know that the clock changes sometimes?
