Embed Notice

@clacke @drahardja @lispi314 I wrote code in the early 1980s that took full notice that two-digit year fields were a liability and that some folks who were in the datasets were possibly *born in the 1800s* and that the dataset might endure past the end of the 1900s or require forward calculations into the then-distant 2000s. Agreed there were some systems that had so little memory that date compression was needed, but we used binary fields for time, not truncated text dates.
