Re: Measuring time intervals using Time::HiRes -- time vs. gettimeofday and tv

Here's the source for tv_interval:

sub tv_interval {
    # probably could have been done in C
    my ($a, $b) = @_;
    $b = [gettimeofday()] unless defined($b);
    (${$b}[0] - ${$a}[0]) + ((${$b}[1] - ${$a}[1]) / 1_000_000);
}

That should explain everything, I think.

It's all fine and dandy until someone has to look at the code.
