Everyone seems to be considering number solutions when I see a string

$year = substr ($year, -2);
One must consider performance of converting to and from string to
number by perl. If $year is always treated as a number, then you save
yourself from auto-conversion to string and back. Also, what happens
when year is only 1 digit (of course, this should not happen in MHonArc
unless an incorrect date is put on a message).
However, in this case, it is not a real issue. But it is good to
know about it when programming in Perl if performance is a real
concern.
