I think this is based on a misunderstanding of the damage that
the DIR EXEC does.   It never looks at the dates on *files*;
it looks at the current date (via QUERY TIME), and if the last
two digits of the year are greater than 89, it will erase all
files with mode a0 or a1, regardless of the dates on the files.
Changing dates on files will have no effect on how DIR behaves.
