The fact is that another generation will have to die before the
teachers, students, textbooks and software written by them get
accustomed to the fact that time is not longitude.

longitude and latitude belong to the IERS.

It is the context for understanding other things.

In there I do not find the ITU-R's Radio Regulations, so perhaps the
whole point of this mail list is moot, for we are not bound to follow

In there I also do not find Meter Convention, so perhaps the UN list
is not comprehensive. The Meter Convention does say this
and the context for that is CCIR Recommendation TF.460-1. I believe
that revision of TF.460 specifies a tolerance of 1 second as well as
saying "GMT".
