The >only reasonable use of Calendar in Ada is for inexact, convenient >"match the wall clock" use. The only reason Ada.Calendar.Clock would not normally be monotonic is if some human decides so. A missile during flight does not normally worry about time zones. If someone creates a file, then sets back the clock and creates another file (or programs his computer to set back the clock), that's hardly a design error in Ada. It would make more sense to call it a design error that wall clocks don't read in UTC, but need to be adjusted when you move, or twice a year even if you don't move. Now *that's* goofy.
