Hello Elias,

Ok. 

First solution: use previously mentioned ")set message time on".


Second solution: update Renaud's TIMER package.
 http://ftp.lip6.fr/lip6/softs/formel/Axiom/Misc/timer.spad.gz

GCTIME should be replaced by GCL SI::GBC-TIME (thank you Camm). 

  Function: GBC-TIME (&optional x)
      Package:SI

  Sets the internal C variable gc_time to X if X is supplied and then
  returns gc_time. If gc_time is greater or equal to 0, then gc_time is
  incremented by the garbage collector, according to the number of
  internal time units spent there. The initial value of gc_time is -1.


I tried to update the package but there is an issue with the SI:: common
lisp package prefix.

 Either I use SI_:_:GBC_-TIME()$Lisp syntax, the code compiles but Axiom
 compiler produces |SI::GBC-TIME| symbol which is not recognized as GCL
 function.

 Or either I use SI::GBC_-TIME()$Lisp syntax but in the case the code
 does not compile.

Another point is that a command like ")lisp (si::gbc-time 0)" should be
entered at package initialization to enable gbc-time computation.

Last point, one should use INTERNAL-TIME-UNITS-PER-SECOND from Lisp to
get the transform returned number into seconds.

 Constant: INTERNAL-TIME-UNITS-PER-SECOND
     Package:LISP The number of internal time units that fit into a second.



Sorry, I cannot help you further, what your are asking is beyond my
knowledge. As he proposed to you, Tim will help you.


Yours,
d.
