So is it barred by treaty from providing the information? I don't see how
any of these treaties are relevant.

But the key here is that the *DATABASE* is comprised of thousands of data
and what US agencies are supposed to and not supposed to provide is
irrelevant to the argument. The leap seconds are part of the time database,
just like knowing  that the first Saturday in November is the time shift in
the US.

Again, since we're talking about a database, this is not an argument with
any merit. The entire database is comprised of data from many things that
should be provided elsewhere. What makes the leapsecond data unique? How is
it fundamentally different than the rest of the offset data in this
database? There's a time that the offset is valid, and an offset.
Fundamentally, that's no different than the other offset data. I fail to
see the relevance of the US law angle at all. There's nothing in US law
that precludes others from providing it. There's nothing in US law that
requires people to get this data from any source at all. There is US that
says so and so should provide it, but again, that's doesn't preclude others
from also providing it.

What's the damage? This is a time database provided on an as-is basis for
the purposes of allowing time datum to be exchanged and displayed in a
pleasing format to local users.
