Just as an aside, UNIX time_t values are not an appropriate representation
of time in a distributed system.  An ASCII rendition of UT is much better.
As such, it doesn't really matter that some systems are accounting for leap
seconds or not(*), just like it doesn't matter if some are DEC System-20's
with a different base representation.  Each system only needs to convert to
and from its own representation.

(*) those that don't understand leap seconds may have some trouble with
    "87/12/31 23:59:60", although I wouldn't be surprised if they just
    ended up with "87/12/31 23:59:59"+1.
