This method, for the nth time, does not convert between units which do not

I'd also point out that it probably won't work well with non-integer
units. I'm not sure what'll happen
Dave,
Thanks for the reply. So are you saying that DateTime::Duration
shouldn't really be used at all if I have units of fractional anything and
want to convert that to a duration? I'm supposed to convert it first to
hours, minutes and seconds and then instantiate a DateTime::Duration from

Yeah, I need to make that clearer. The problem is that with leap seconds,
there are a few 3601 second hours out there.
Now it becomes clear.
As a related aside. What is wrong with addiing 160.2 minutes to
I once wrote a module to do this (long before DateTime).
Note that in the second case the result is exact.
Date::Tie is _very_ careful to round errors correctly.
use Date::Tie;
tie my %date, 'Date::Tie', frac_hour = 2.67;
print $date{frac_hour}, \n;
print $date{hour}, :,
Hi Tim,
It looks like the normalization is hosed.
Cut 'n Paste-able example:
--
use DateTime::Duration;
my $dur = DateTime::Duration-new( hours = 2.67 );
print hours: ,$dur-in_units( 'hours' ), \n;
print minutes: , $dur-in_units( 'minutes' ), \n;
print seconds: , $dur-in_units(

How can that be sane? So you ask for minutes and you get fractional
minutes but you ask for seconds and get zero?
Cause really it should just blow up when you give it fractional anything.
Or not. Anyone know of a good way to check that a parameter is one

Whooo, I seem to have missed the bus here. Wasn't the entire point

Maybe it could be something like DT::Duration::Fractional? What do others
think?
A variant of Duration that assumes standard lengths for day, minutes, hour
etc, and with a caveat that it will always add seconds when
