No. The time_t used by xntpd and other leap-second-ignorant applications
is not UTC. It jumps backwards. It cannot be reliably converted to UTC,
or to any other standard astronomical or legal timescale. It cannot be
used reliably by programs that subtract or otherwise compare time_t
values. It is an embarrassment to the UNIX community.

Describing the xntpd time_t as UTC gives the xntpd time_t an air of
legitimacy that it doesn't deserve.
