So is that a bug in DateTime? If I subtract one epoch time from another and
add shouldn't they end up together? Or is it just too weird to code for?

Maybe a better solution than adding seconds would be just moving to that
epoch slice, I'd have to create a new datetime using from_epoch (unless
there is a way to do that on an existing object other than date math) but
it would remove any math inconsistencies.

I was wondering about leap seconds since it only happened in that one time
frame but wasn't sure where to check for it, thanks.
