Perhaps I might expand on some of Bill Thompson's statements in the context of the great convenience factor of using the current UTC standard.The accuracy requirement for the delivery of UTC to the instruments is +/- 0.410 seconds.High quality, cutting edge science doesn't always require

On the other hand, even if we agree on one standard, or even just

to abandon UT1 ?
If so, then this is the first I've heard

Now, what we you mean by civil time standard ?
Most countries reserve the definition of civil time for their
national parliaments (or other some other tacitly assumed legitimate
political power).
They generally take UTC, apply a timezone

I've appended what I call the Civil Time Decision Tree v0.5.
Reminder - the intent is to provide a scaffolding for characterizing
any possible civil time standard (whether practical or not). Please
