I need to do some computations involving seconds between two dates. AFAIK,
there is nothing specific in the ARM related to the package Calendar that an
implementation is required to account for leap seconds. Consider the
following computation:
Some_Duration := Time_Of (1996, 1, 1, 0.0) - Time_Of (1980, 1, 6, 0.0) ;
I'd guess that an implementation having a big enough Duration would almost
certainly consider leap years in this computation, but leap seconds might
not be required or implemented. Across relatively small spans of time, it
probably doesn't matter and certainly if one is only doing relative timing
(deltas) it doesn't matter at all. However, across larger spans, it could be
enough to make a difference. Does anyone know if it is required?
