The standard time broadcasts contain estimates of DUT1, the diff
The astronomers on this list have had no qualms about providing
concrete examples of how their systems work and why they would break
if leap seconds were stopped. Aside from GLONASS, those who wish to
abolish leap seconds have not concreately identified the systems which
don't like leaps. This is
