I don't see why you would think that?

D.8(19):
  "The Time value I represents the half-open real time interval
   that starts with E+I*Time_Unit and is limited by E+(I+1)*Time_Unit,
   where Time_Unit is an implementation-defined real number and E is
   an unspecified origin point, the epoch, that is the same for all
   values of the type Time. It is not specified by the language
   whether the time values are synchronized with any standard time
   reference. For example, E can correspond to the time of system
   initialization or it can correspond to the epoch of some time
   standard."

In GNAT Ada.Real_Time.Time is bitwise identical to Ada.Calendar.Time
(which I believe to be a mistake, but quite hard to fix).
