%let start=%sysfunc(datetime());

proc report data=sashelp.cars;
column origin n;
define origin /group;
rbreak after / summarize;
define n / "";
compute after;
  origin = "Total";
endcomp;
run;

%let end=%sysfunc(datetime());
%let duration = %sysevalf(&end. - &start.);
%put Duration = &duration. seconds;

Try this

%let t1 = %sysfunc(datetime());

data _null_;
   x=sleep(10,1);
run;

%let t2 = %sysfunc(datetime());

%let run_time = %sysevalf(&t2 - &t1);

%put &run_time;
