Not an impossible threat but even though a lot of people put a shitload of person hours identifying and fixing issues the credit card systems failed come 12:00:01 in New Zealand but by the time Eastern Australia reached that time the software had been fixed. Not many Hospital systems used dates as part of their therapeutic function but they often use dates for the logging and reporting functions and when a buffer overflows by 1 byte (because 100 is 3 digits instead of two) sometimes configuration data could be overwritten. The simple answer was to reset the dates for this equipment back 20 years.
