[pkg-ntp-maintainers] Bug#858548: ntp: Use of CLOCK_TAI should return correct value

[Edmund Grimley Evans]

Source: ntp
Version: 1:4.2.8p10+dfsg-1
Severity: wishlist

I posted a question to debian-users
(https://lists.debian.org/debian-user/2017/03/msg00591.html) and
nobody said "This already works" or "This is a bad idea", so I'm
filing this bug.

It would be nice if clock_gettime(CLOCK_TAI, ...) would give the
correct answer either with no special configuration or with very
little extra reconfiguration. This would probably be achieved by
downloading a table of leap seconds so it is related to #851096.

A test program to print out the difference between CLOCK_TAI and
CLOCK_UTC or CLOCK_REALTIME is attached. (Right-justification of
this bug report happened by accident.)
