Have you run this with use warnings; use strict;? When I do I get: 

Pseudo-hashes are deprecated at noname2.pl line 41.
Argument "2005-11-07 11:18:01" isn't numeric in hash element at noname
+2.pl line 41.
Use of uninitialized value in split at noname2.pl line 41.
Use of uninitialized value in hash element at noname2.pl line 41.
Use of uninitialized value in anonymous hash ({}) at noname2.pl line 4
+1.

which sort of indicates a problem. Note that this happens even if I replace the undef values with values.

Perl is Huffman encoded by design.
