Note L</format_duration_between>(), does not suffer from this since we're using a specific DateTime object already.

    print $span->format_duration_between( $dt, $dt->clone()->add('seconds'=> 62) ); # 1 minute and 2 seconds

=head2 Why do you put a comma before the 'and' in a group of more than 2 items?

We want to use the so-called Oxford comma to avoid ambiguity.

=head2 My DateTime::Format::Human::Duration::Locale::XX still outputs in English!

That is because it defined neither the L</get_human_span_hashref()> or the L</get_human_span_from_units()> functions

It must define one of them or defaults are used.

=head2 Why didn't you just use 'DateTime::Format::Duration'

Essencially DateTime::Format::Duration is an object representing a single strftime() type string to apply to any given duration. This is not flexible enough for the intent of this module.

DateTime::Format::Duration is not a bad module its just for a different purpose than DateTime::Format::Human::Duration

=over 4

=item * It was not localizable

You either got '2 days' or '1 days' which a) forces it to be in English and b) doesn't even make sense in English.

You could get around that by adding logic each time you wanted to call it but that is just messy.

=item * Had to keep an item even if it was zero

If 'days' was in there you got '0 days', we only want items with a value to show.

That'd also require a lot of logic each time you wanted to call which is again messy.

=item * This module has no need for reparsing output back into an object

Since the datetime info for 2 points in time are generally in a form easily rendered into a DateTime object it'd be silly to even attempt to store and parse the output of this module back into an object. 

Plus since it all depends on the locale it is in it'd be difficult.

=back

The purpose of DateTime::Format::Human::Duration was to generate a localized human language description of a duration without the caller needing to supply any logic.
