These methods return numbers indicating how many of the given unit
the object represents, after having taken away larger units.
The key here is "after having taken away larger units"
using your example you were expecting the days unit to
be set to 18 however, that can also be expressed as 2 weeks
and 4 days. Which is what DateTime is doing:
use strict;
use warnings;
use DateTime;
use DateTime::Format::MySql;
my $start_date = DateTime::Format::MySQL->parse_date( '2005-01-05' );
my $end_date = DateTime::Format::MySQL->parse_date( '2005-01-23' );
my $dur = $start_date->delta_days( $end_date );
print "Number of weeks is:",$dur->weeks ,"\n";
print "Number of days is:", $dur->days;
prints
F:\scripts>my.pl
Number of weeks is:2
Number of days is:4
F:\scripts>
So what is needed is a way to tell DateTime to convert all units
to just one, in your case days. Hence the in_units method
needs to be used. I hope this helps.
