I have heard this argument from software developers over and over again - not one of whom has ever actually worked through a shift in an ICU or critical care, or med-surg ward. I doubt if any of them have ever worked ANY shift work that spanned a clock change. The problem is not in the representation of time values in the system, it is in the system-human interface, and the actual work in the hospital that is tied to wall clock time. 2:30AM means something to these workers and patients, and having a shift or day when there are two 2:30AMs, or no 2:30AM f**s things up. That the software is poorly designed to support the change exacerbates the problem, but isn't the actual cause of it.
