Re^3: Timer subtraction

[haukex]

Format duration is not working for me. In the last 3 print statements you are using format_duration which is not supported. Unfortunately, your code snippet fails.

The code snippet works fine for me. How does it fail for you? Please see How do I post a question effectively? and I know what I mean. Why don't you? - what are the exact error messages you get? Perhaps you have to install DateTime::Format::Duration?

Even if not, you can still access the fields of the DateTime::Duration object yourself. This outputs the same thing as my above code:

sub my_fmt_duration {
    my @t = shift->in_units('hours','minutes','seconds','nanoseconds')
+;
    $t[3]/=1000000; # ns->ms
    return sprintf("%02d:%02d:%02d:%03d",@t);
}

print my_fmt_duration($first),"\n";
print my_fmt_duration($last ),"\n";
$last->subtract_duration($first);
print my_fmt_duration($last ),"\n";
