This, however, is an example of an unhelpful statement. You may (or,
obviously, may not) agree with statements from others on the list. If
not, by all means make a passionate response. But it is not only
rude, but counterproductive to try to tell others what they can or
cannot say.

For instance, I happen to think your notion about perpetually
revolving the time zone offsets around the planet under completely
local authority is spectacularly unworkable. However, you have my
encouragement (and more to the point, don't need it) to keep trying to
develop supporting arguments for it.

On the other hand, I won't seek to justify the basis of Steve's
message because we have done so over and over.

When some say "civil time" they mean the underlying international
timescale (UTC or not, but currently everywhere some approximation to
GMT). When others say civil time they mean local standard time. One
is obviously layered on the other (whatever chaos might be introduced
by standards bodies, and whether or not time zone offsets are a
function of time), and the particular meaning is almost always clear
from the context of a particular message.
