OK thank you everybody for these explanations.
My problem is to save the time of computing, because my aim is to compare
by simulations several methods, notably to compare them over the time of
computing. These method are very long to run (several hours for one of
them, several dizains of minutes for two others, seval seconds for the
four last), and I so, the displaying of the time of computing is not
enough for me: I must save it.
The rmsg and profiler command don't permit a priori to save this time of
computing. Since the simulations can run over several days, I must
consider the problem of the date, so the problem is complex.
The elapse command seem to be a solution, as the time of computing can be
saved in a global macro ($S_elap) even the obtained result is strange (111
means 1 minute and 11 seconds !!). I test it.
So thank you to Antoine, Ulrich, E. Leuven, Davis and Nick for their help
to solve this problem.

My problem is to compute the time between the beginning and the end of
the running of a program.
Thank you for your help.

As you mentioned in your earlier message, you can take the time using
$S_TIME (or, equivalently, c(current_time) ).
I'm usually content to just display them and mentally take the
difference. But it is possible to automate this. You would need to
textually take apart the time value into its components, and convert to
numbers. Thus:
local time1 = c(current_time)
scalar hour1 = real(substr("`time1'", 1, 2))
scalar min1 = real(substr("`time1'", 4, 2))
scalar sec1 = real(substr("`time1'", 7, 2))
Do the same for another moment in time.
Then you need to subtract them. The easiest way would be to convert
them into seconds (within the day): hour1 * 3600 + min1 * 60 + sec1.
Of course, there are complications if the run spans different days. I
leave that to you.
Good luck.
