Subject: Defend Decode_Date_EU/US against year being warped due to window move

These functions are defined to be floating relative to the current year
based on the result of the moving window function where the full year
is itself, unclear.

This prevents the tests failing spuriously due to the calendar rolling
over.

Bug: https://rt.cpan.org/Ticket/Display.html?id=114375
