Which meetings? I mean, what standards body?

These are the sorts of details that should be hammered out in advance - and it has never seemed controversial among any of the stakeholders that reliable information should be provided in a good format using flexible protocols implemented on scalable hardware with robust network connections.

If I understand the provenance, BIPM is responsible for maintaining 
atomic time and TAI, IERS is responsible maintaining for UT1 and Leap 
Seconds, and ITU is responsible for "time dissemination". Whats not so 
clear, and it would be reassuring to know, is how the information is 
officially shared between these bodies and to what degree its automated.

If ITU is responsible for "time dissemination" it would seem like they 
should also be responsible for "time metadata dissemination", ie: Leap 
Second announcements, history, and related.
