It is all too common to find situations where it is difficult to
ascertain who has authority, over what geographic region, and what
exactly they are trying to say.
I've looked at the report and it is bad social science. The protocols are
too leading to provide reliable information. Basically, from a
methodological perspective, the deck was stacked in this research to
ensure the results it obtained.
That said, the report does reflect a dominant opinion of
I think the dialog shows one thing clearly: The UK's historical
zero offset from UTC has made it very hard for them to generalize
that this is not a law of nature.
It is certainly clear that very few involved realized that UK could
run on a non-zero UTC offset, without any more harm to

In the Judeo-Christian tradition, the relevant verse is Genesis 1:14 which says
that the sun and moon are to be used to mark the times, days, and years.
That said, in Orthodox Judaism, mean time is seen as at variance with this
teaching. The prayers are set to zmanim—times that vary with the
Hello Kevin.
The information specifying that for Japan the next Leap Second will be
applied Wednesday, July 1, at 9:00. is interesting in that this is the
first official policy on when the Leap second shall be applied to a
local timescale. Maybe I have been looking in teh wrong places.

The leap second happens world wide in UTC at 23:59:60. Since all time zones

it is whatever time that is offset from UTC. Otherwise, the offset would no

Hi Stephen,
You're not looking in the wrong places. In fact there is no need to look at all.
Local time is conventionally (legally) an offset from UTC and so if/when UTC
steps so does local time. There is no need for a local decision or
international standards in this regard. Everyone living
Many aspects of local time or civil time are left to common
practice which is not good enough to expect uniform inter-operable
implementations.
Brooks, can you give some examples?
We here concentrate on discussions of UTC and Leap
Seconds, which is foundational, yet obviously local time
Watching the video interviews on that site, with the members of the public,
I was disappointed that most of them seemed unaware of any technical
problems the leap-seconds cause. I think the team running those sessions
did the whole idea a dis-service by not making those problems clearer :-(
