+=head1 NAME
+
+SL::DB::Helper::AttrDuration - Attribute helper for duration stored in
+numeric columns
+
+=head1 SYNOPSIS
+
+ # In a Rose model:
+ use SL::DB::Helper::AttrDuration;
+ __PACKAGE__->attr_duration('time_estimation');
+
+ # Read access:
+ print "Minutes: " . $obj->time_estimation_as_minutes . " hours: " . $obj->time_estimation_as_hours . "\n";
+
+ # Use formatted strings in input fields in templates:
+ <form method="post">
+ ...
+ [% L.input_tag('time_estimation_as_duration_string', SELF.obj.time_estimation_as_duration_string) %]
+ </form>
+
+=head1 OVERVIEW
+
+This is a helper for columns that store a duration as a numeric or
+floating point number representing a number of hours. So the value
+1.75 would stand for "1 hour, 45 minutes".
+
+The helper methods created are:
+
+=over 4
+
+=item C<attribute_as_minutes [$new_value]>
+
+Access only the minutes. Return values are in the range [0 - 59].
+
+=item C<attribute_as_hours [$new_value]>
+
+Access only the hours. Returns an integer value.
+
+=item C<attribute_as_duration_string [$new_value]>
+
+Access the full value as a formatted string according to the user's
+locale settings.
+
+=item C<attribute_as_man_days [$new_value]>
+
+Access the attribute as a number of man days which are assumed to be 8
+hours long. If the underlying attribute is less than 8 then the value
+itself will be returned. Otherwise the value divided by 8 is returned.
+
+If used as a setter then the underlying attribute is simply set to
+ C<$new_value>. Intentional use is to set the man days first and the
+ unit later, e.g.
+
+ $obj->attribute_as_man_days($::form->{attribute_as_man_days});
+ $obj->attribute_as_man_days_unit($::form->{attribute_as_man_days_unit});
+
+Note that L<SL::DB::Object/assign_attributes> is aware of this and
+handles this case correctly.
+
+=item C<attribute_as_man_days_unit [$new_unit]>
+
+Returns the unit that the number returned by L</attribute_as_man_days>
+represents. This can be either C<h> if the underlying attribute is
+less than 8 and C<man_day> otherwise.
+
+If used as a setter then the underlying attribute is multiplied by 8
+if C<$new_unit> equals C<man_day>. Otherwise the underlying attribute
+is not modified. Intentional use is to set the man days first and the
+unit later, e.g.
+
+ $obj->attribute_as_man_days($::form->{attribute_as_man_days});
+ $obj->attribute_as_man_days_unit($::form->{attribute_as_man_days_unit});
+
+Note that L<SL::DB::Object/assign_attributes> is aware of this and
+handles this case correctly.
