Well, Yanick, I presume your comment "like we can do in C" means calling 
the strftime function defined in <time.h>?

Ada.Calendar does NOT define any formatting for time values. If you want
to format time values, you will have to write your own "time-to-string"
function, or else scrounge up a copy of Wizard Ware's Calendar Utility
package (see "Software Components with Ada", G. Booch). Or, you could
search
the public domain libraries for Ada calendar formatting packages.

Good luck!

Package Calendar _does_ return the date.

declare
   Year  : Year_Number;
   Month : Month_Number;
   Day   : Day_Number;
   Seconds : Day_Duration;
begin
   Split 
     (Date => Clock,
      Year => Year,
      Month => Month,
      Day   => Day,
      Seconds => Seconds);
end;


I'm not clear if you meant just "get the date," or if you meant, "get a
time string whose format is like that in C."

If you meant the former, then Calendar.Clock does the trick.

If you meant the latter, then there are utilities you can use to create
a string representation of time, in various formats.  Check the PAL.
Check DejaNews too - I think this question was asked recently, and
someone named an actual unit in the PAL.
