Question

In Perl:

my ($usr,$sys,$cusr,$csys) = times;
printf "real %s, user %s, sys %s\n", $usr + $sys, $usr, $sys;

Is this true? I read some other questions where people did things like saving the current time away in a variable and collecting it later, but why wouldn’t this work?

Answer 1

C:\Temp> cat tt.pl
sleep 5;
my ($user, $system) = times;
print "u = $user s = $system\n";


C:\Temp> tt
u = 0.015 s = 0.015
