There is an easy way to understand -> (at least I hope so):

$something->func($x);

[download]

is nearly the same as

func($something,$x);

[download]

with func a subroutine out of the package (called class) that $something belongs to

There is also an easy way to understand printf:

printf("bla %xyz chink %ru wong",$a,$b);

[download]

is somewhat equivalent to

print "bla $a chink $b wong";

[download]

The printf often does some conversions of the variables, but basically thats it.

Now in the code someone on IRC gave you the printf is not the normal builtin perl printf, since it was called with the -> syntax. Instead it must be subroutine out of the package $t belongs to. What package does $t belong to? Date::Manip::Delta, since $t was created with my $t = Date::Manip::Delta->new;

UPDATE: Added the word 'nearly'
