Re: Ada.Real_Time Vs. Ada.Calendar

In general, you can't count on them having any meaningful relationship. Real_Time may be a count of ticks since the program started, for example, while Calendar must be a date and time CE.

How they are implemented is not specified, which is not surprising.

For a specific compiler and platform, you may be able to make use of compiler-dependent information to relate the two. GNAT, for example, defines both Time types as "new Duration". That doesn't guarantee that the stored values have the same meaning, though.
