have no idea why you have the 30-second delay at the end of the program,
but it would make the execution time of the program exceed 90 seconds."
My apologies. I accidentially posted the code that I used to test the
accuracy of the delay statement itself, which, as your results showed, is
fairly accurate.
The code should have read:
*********Begin Code*****************
with Ada.Real_Time; use Ada.Real_Time;
with Ada.Text_Io;
-- with Ada.Standard;
procedure TestTime is
-- ----------------------------------------------------------
-- GET THE STARTING TIME, LOOP, GET THE END TIME, SUBSTRACT
-- ----------------------------------------------------------
Time_Start : Ada.Real_Time.Time;
Time_End : Ada.Real_Time.Time;
Time_Difference : Ada.Real_Time.Time_Span;
Time_Duration : Standard.Duration;
begin
Time_Start := Ada.Real_Time.Clock;
for I in 1..17400 loop
delay 0.003448275862;
end loop;
Time_End := Ada.Real_Time.Clock;
Time_Difference := Time_End - Time_Start;
Time_Duration := Ada.Real_Time.To_Duration(Time_Difference);
Ada.Text_Io.Put("Time Difference: ");
Ada.Text_Io.Put(Duration'Image(Time_Duration));
delay 30.0;
end TestTime;
***********End Code************
