I think all that page is propsing is using the date of the file
creation rather than the current date. Both windows 'move'.
I suppose I can consider adding a year parameter to the thing (at some
point in the future, first I want to get the basic functionality
working without too many feeping creatures). Also I will consider a
pedantic flag that will enable some warnings about ambiguous dates (or
perhaps a flag to prevent use of ambiguous dates). But that will all
be later...
