I'll offer one reason.

Using 32-bit integers the Unix epoch ends in January 2038.
The widespread deployment of 64-bit systems has yet to come.

It would be a Really Good Thing (TM) if the understanding of 64-bit
Unix time were implemented in a fashion more conformant with the
reality of leap seconds than the current 32-bit definition is. The
protocols necessary to do this in a robust fashion need to be
determined ASAP.

It would be nice to see some responses from respected members of
the timing community.
