Return to year format problem (thing)

Given that different localities use different [date format]s, and given that in ##/##/##, we use little heuristics to figure out which end's up, going to a [one digit year number] might, at first-blush, seem to be confusing, but (a) it's fairly safe, and (b), for roughtly two-thirds the time, [MM/DD] and [DD/MM] are indistinguishable anyway. Besides, we don't have day zero or month zero anyway.

I don't know if it's an [imaginary problem] or a [real problem], but I remember losing some bandwidth to it [a few years back].
