It's actually precisely the reason I wanted to do it. The change of data
with time is just as useful, in the same way as the map you printed
yesterday won't be the same as the one you print today. We don't have a
clear method of differentiating data by era at present so I wanted to look
at that aspect. One of my uses for OSM data relates to genealogy which needs
maps from different epoch's.
