[LEAPSECS] LEAPSECS Digest, Vol 25, Issue 5

[Jonathan Natale]

Does anybody have any thoughts on the effect(s) of the previous and/or
upcoming leap seconds on NTP (v2, v3, and/or v4)?  For example, on
protocols that implement sub-second timers (such as BFD)?  TCP?  IGMPv3?

I got this claim from "Calendrical Calculations" which says:

	The concern that the date of Passover would influence the date
of
	Easter goes back to the easliest days of Christianity. For
	example, Eusebius (Vita Constantini, book iii, 18-20) gives a
	letter of the Emperor sent to those not present at the Council
of
	Nicaea:

		When the question relative to the sacred festival of
		Easter arose ... [it] was declared to be particularly
		unworthy for this, the holist of all festivals, to
follow
		the custom of the Jews ... We ought not, therefore, to
		have anything in common with the Jews ... we desire,
		dearest brethren, to separate ourselves from the
		detestable company of the Jews, for it is truly shameful
		for us to hear them boast that without their direction
we
		could not keep this feast. How can they be in the right,
		they who, after the death of the Saviour, have no longer
		been led by reason but by wild violence as their
delusion
		may urge them? They do not posess the truth in this
Easter
		question ... it would still be your duty not to tarnish
		your soul by communications with such wicked people.

	Avoiding Pasover was also evident in the Gregorian reform of the
	Easter calculation. Canon 6 of the Gregorian calendar, published
	in 1582 and probably written by the German Jesuit astronomer
	Christopher Clavius, says so twice: in the last sentence of the
	first paragraph

		ne cum Iudaeis conveniamus, si forte dies XIV lunae
		caderet in diem dominicum

		[so that we would not come together with the Jews if by
		chance day 14 of the moon may fall on a Sunday]

	and in the middle of the second paragraph

		Ne igitur cum Iudaeis conveniamus, qui Pascha celebrant
		die XIV lunae, ...

		[Hence so that we would not come together with the Jews
		who celebrate Passover on day 14 of the moon, ...]

One might take exception to the author's assertion that the Council of  
Nicaea was the earliest days of Christianity - considering it didn't  
take place until the year 325.  I've appended some timeline entries  
for AD 1683 to show what can change and remain the same over 325  
years.  (Various harbingers of today's world, as well as echoes of  
Nicaea.)  I recommend listening to the empyrean Purcell from 1683 to  
put the rest of my more pedestrian message into its best context :-)

	http://www.youtube.com/watch?v=LLn-35h3V3g

Sidestepping the disturbing anti-semitic history of our calendar,  
there is indeed a useful insight one can draw from this analogy with  
the Council of Nicaea.

 From Wikipedia:


> The Council of Nicaea was historically significant because it was  

> the first effort to attain consensus in the church through an  

> assembly representing all of Christendom.[3]


We can draw the insight, namely, that 1683 years later, we still  
remember its occurrence as historically significant and honor its work  
products:

	God from God, Light from Light,
	true God from true God,
	begotten, not made,
	of one Being with the Father.

(From the 1975 ecumenical translation.)  Not bad for poetry written by  
committee.

We remember the Nicene Creed and the Council that created it -  
precisely because Constantine sought consensus BEFORE decision-making,  
not after.

One seriously doubts that the work products of ITU-R WP7A will be  
remembered as long or will be regarded as poetic.  What is more  
lyrically elemental than time, however?

Surely it is in the interest of all parties to pursue a truly robust  
consensus.  As with the 1884 International Meridian Conference, echoed  
by the 1993 Longitude Symposium at Harvard, it is now time to organize  
an ecumenical (that is, broadly conceived and broadly attended)  
conference on civil timekeeping.

The alternative to doing so will be an awkward, fragile, and cramped  
decision, well short of consensus - immediately to splinter and  
ultimately to shatter.

It appears that some have taken the message from the 2003 Torino  
meeting that civil timekeeping is an obscure topic of little interest,  
with unbridgeable factional differences.  A more generous  
interpretation is that even on short notice, in a distant city, with  
an obscure title ("The ITU-R SRG 7A Colloquium on the UTC timescale")  
that still three dozen interested parties (from just one narrow  
segment of the broader "community of time") attended due to their  
perception of the key importance of the topic.  They were also able to  
reach an interim consensus (roughly "don't be hasty" and "call it  
something other than UTC if it IS other than UT"), that should inform  
future discussions.

A well advertised meeting in London or Washington (ie., one plane hop  
from either side of the Atlantic), planned a year or two in advance  
(as other scientific meetings are), promoted assiduously by a broad- 
based organizing committee (I nominate Steve Allen), would provide the  
foundation for actually accomplishing the underlying goal of devising  
a coherent long term plan for worldwide civil timekeeping.

This is also the quickest practical way to reach such a goal:
	"Let us enjoy the benefits of the time - but rather the benefits
of  
their own valour and prudence, for time drives everything before it,  
and is able to bring with it good as well as evil, and evil as well as  
good."
					- Nicolo Machiavelli

(Exercise for the student:  Contrast Nicolo and Nicaea with Penn's  
son's "Walking Purchase" of land from the Lenni Lenape/Delaware.  "Not  
sworn to, nor broken"?  Maybe in 1683 while Penn himself was still  
around.)

outnumbered Christian troops, spurred them to victory. The Turks left  
behind sacks of coffee which the Christians found too bitter, so they  
sweetened it with honey and milk and named the drink cappuccino after  
the Capuchin order of monks to which d'Aviano belonged. An Austrian  
baker created a crescent-shaped roll, the Kipfel, to celebrate the  
victory. Empress Maria Theresa later took it to France where it became  
the croissant. In 2006 John Stoye authored ?The Siege of Vienna.?
