The documented upper limits for the date part of serial date times match 9999-12-31 00:00:00, which is correct, but could be supplemented for the sake of extensive clarity by a mention of the absolute upper limits for serial date times, that would match 9999-12-31 23:59:59.

Add a mention, possibly in an informative note, that the upper limit on date time serial numbers match 9999-12-31 23:59:59, and precise the corresponding serial numbers as appropriate (depending on the date base).
