Subject: RE: BS: Brexit #3: A futile gesture?
Having got interested in the subject now, ISO 8601:2000 defined how two digit years were interpreted, but this is no longer a standard. Excel interprets years 00-29 to be 2000-2029 by default, but this is changeable. Other systems use a different 'change over point'. IBM use 40 so 00-39 are interpreted as 2000-2039 and 40-99 as 1940-1999.   

I have not found a system that thinks 19 represents 1919 yet, and don't think it worth exploring further.
