This is your problem. The offset on 1970 Jan 01 00:00:00.00 was -6 hrs.

Of course, any attempt to relate an Ada.Real_Time.Time to an Ada.Calendar.Time 
is completely compiler dependent, is unlikely to work with any other compiler, 
and could stop working with a different version of the same compiler.
