Both POSIX and NTP use UTC.  Your problem is that you are not using
using UTC, but, rather, using TAI.

The ntpd source code is available, and it would probably be fairly easy
to either:  produce a system dependencies module that translated UTC
to TAI and let the OS insert the leap seconds; or to remove all the
leap second code and convert reference clock times to TAI; however,
the second version would be dangerous and you would need to modify the
port number, and, if possible, make the packet formats incompatible,
to prevent it being mistaken for a real NTP server.
