I watched my Tru64 5.1B and Linux 2.2-2.6 servers (NTP wasn't running on
my Solaris 9 server accidentally) and Juniper and Cisco gear, and they
all stayed in sync.  The Linux systems logged:

Dec 31 17:59:59 kosh kernel: Clock: inserting leap second 23:59:60 UTC

17:59:59 lasted 2 seconds in local time (since the normal time zone data
doesn't pass through leap seconds).

I saw the following from JUNOS:

Dec 31 18:00:00  hsvrouter /kernel: microuptime() went backwards (8144133.847075 -> 8144132.881330)

Tru64 and Cisco didn't log anything.

I don't speak for anybody but myself - that's enough trouble.
