The real benefit of this is that for the next hundred years or so, you can continue to set your VHS Recorder's clock / calendar, which has only a two digit year. Some of them display weak day calculated from the year. So always setting the calendar year back by 28 years, for years after 2000 can extend your VHS unit's life an extra century or so.
