I agree. I think the basic datetime object should ignore this issue
(properly documented), and leaving room for someone writing a
datetime_leapsecond object, that would be aware of them. Avoiding this
issue we can achieve a better performance and a simpler code base, with
enough functionality for most practical purposes.
Another point that should be noted: as stated earlier, the leap seconds
cannot be predicted, they require a frequent update, making replicability
difficult: the same code in two machines with same numpy version, but
updated at different times can produce different results.
