So this is simply a bad data fix up which has essentially no risk of a bad outcome. In the case where the recipient knows of a bad potential outcome for the wrong interpretation, such a date should be rejected ... (I don't feel a need to > say this in the spec). If we're going to disallow producing these dates when HTTPbis publishes, it seems like it would be reasonable to choose a fixed date -- say, Jan 1 2050? I doubt that any valid HTTP messages were generated before 1950, and I *hope* that any remaining implementations that generate two-digit dates will be gone by 2050...
