However I get an error from this.

As per the error message ;--) $catalog_timestamp is in scope in the main
sub, but not in the rest of the file.
2 options: make it global to the file by declaring it outside of the
main sub, or (cleaner), pass it to the handler via a closure:
my $catalog_settings= XML::Twig->new(
twig_handlers => {
'Item' => sub { get_catalog_field_names( @_, $catalog_timestamp); }
...
sub get_catalog_timestamp {
my ($twig, $elt, $catalog_timestamp) = @_;
...
Does this help?
