I’ve got 99 problems, and they’re all dates.
Art Tracks is a project for the Carnegie Museum of Art, tracking the history of ownership for fine art. As part of this, we’ve had to deal with date problems unlike those of most technology projects—problems such as dates like “sometime after 1995” and “Possibly the fifteenth century” .
Ruby and the date_time_precision gem have been an invaluable tool in helping to maintain and manipulate the very specific information contained in these historical records.
