If a filename contains a timestamp in the form of YYYY-MM-DD-hh-mm,
change the mtime to be the timestamp instead of the one kept by the
filesystem. For example, a valid filename would be
foo-2002-04-01-00-00.txt for April fools day on the year 2002.
It is also possible to use timestamps in the form of YYYY-MM-DD
