Agreed, spent too much time recently trying to get a "modern" database to accept one of out transactional systems' dummy EOT value (3456-02-01).

Took far, far too long for me to realise that it only wanted to store date/time in nanoseconds !? Fuck me, you'd have to be dumb fuck computer to want to measure every date in nanoseconds - even oracle wasn't that dumb, oh hang on we're "upgrading" to MS.

There must be a joke in here to do with dates that only last a nanosecond, I think it's to do with pandas' breeding rates.
