Taking into account e.g. perldoc -q require, the right thing to do should be to require, but if it "doesn't work either", then you should define "doesn't work", which you fail to, it seems to me.

Also, Benchmark.pm can conditionally use Time::HiRes if available, so you may try looking into it to see how it accomplishes to do so...

Update: well, I just gave a peek into the source of Benchmark.pm myself and I can see this:

# --- ':hireswallclock' special handling

my $hirestime;

sub mytime () { time }

init();

sub BEGIN {
    if (eval 'require Time::HiRes') {
    import Time::HiRes qw(time);
    $hirestime = \&Time::HiRes::time;
    }
}
