In zone Africa/Nairobi tzdata has
       2:44:45 - BEAUT 1960

I think this is a typographic error and should be 2:45
Shanks, Gabriel and Le Corre all have 2:45

Could you tell me how to add remove people from the list? I no longer wish to be on it!

Thanks, well spotted.  All 4 instances of "2:44:45"
should be changed to "2:45".  I don't know where those
15 missing seconds came from ...

Tonga standard time changes, attn. Paul Eggert

attention Paul Eggert:
I am reading through the comments for zone Pacific/Tonga
and there you write on 2006-03-22:
... go with Mundell

where "Mundell" means his article by Don Mundell
http://www.tongatapu.net.to/tonga/homeland/timebegins.htm

In reading this article, I cannot see where he places the transition 
from standard meridian 185°e (12:20h) to 195°e (13:00h) into the year 1999.
What I read is that he talks about the change in New Zealand timezone 
from meridian 172.5°e (11:30h) to 180°e (12:00h) on 1946-jan-01, and 
that the Crown prince Tungi, wanted to maintain the 50 minutes 
difference to New Zealand. But it appears that no change was made then, 
in 1946, and Tonga now had only a 20 min difference to New Zealand.

I cannot see how you derive a change in 1999 from what Mundell writes.
Please clarify.

Shanks has this change in 1968, but as usual he gives no source.

PS: does anyone know of a way to get access to old IATA SSIM manuals? I 
rember those being voluminous books which travel agents used to look up 
flight schedules. For several years, I used to collect older copies of 
these manuals from a travel agent and use them to look up timezones, as 
they were documented for each airport, together with begin/end dates for 
DST if such a change fell into the two-month period a manual covered. I 
had a collection of many years from the late 1970ies and the 1980ies, 
but threw them out when I got hold of  Shanks' books. Now I would love 
to check some information in them again, but so far have been unable to

RE: West Bank and the Gaza Strip will have different time zones

1. The "asia" file now shows the switch back to standard time as being at 2:00 on the first Friday in September.
Is the 2:00 correct, or should it be midnight, or one minute after midnight, or something else? And is the
date correct? (Are folks really restarting DST at the end of August and then returning to standard time on
September 3?)

2. Is the zone name "Asia/West_Bank" acceptable?

proposed time zone package changes (Samoa, Kenya, Uganda, Tanzania)

Below find proposed time zone package changes; the executive summary:

	africa		Four instances of 2:44:45 changed to 2:45
			(one in a comment, one each in zones
			Africa/Dar_es_Salaam, Africa/Kampala, Africa/Nairobi)
			(thanks to Jules Descartes)
	australasia	Samoa uses DST in 2011-2012
			(thanks to Laupue Raymond Hughes)

The Samoa changes affect time stamps beginning later this month.

I'm holding off on West Bank and Gaza changes pending further information and
feedback.

If no problems are found, these changes will show up on the ftp site on
2011-09-12.

Re: West Bank and the Gaza Strip will have different time zones

Hi !

> 2. Is the zone name "Asia/West_Bank" acceptable?

According to the file Theory, "names normally have the form 
AREA/LOCATION, where [...] LOCATION is the name of a specific location 
within that region"

West Bank is not a location: it's not a city name, it's not an island 
name. Is there any other name in the database using a territory name for 
LOCATION? If not, why to break this rule?

The next rule is saying: "use the most populous among locations in a 
country's time zone". According to Wikipeida (see [1] below) Hebron has 
the population of 163 thousand people, which makes it to the most 
populated city in the area, so the natural choice is to use 
"Asia/Hebron" as the area name.

(the question whether or not is "East Jerusalem" a location in above 
sense is not really relevant, because the city of Jerusalem is ruled by 
Israeli authorities (if someone likes it or not) and thus the Israeli 
time is used there)

Well said!

This is the best reason to avoid Asia/E Jerusalem that I have seen so far.

We have US/Eastern and friends, though it is via a link. The obvious
answer to "why" is that it would be politically expedient and avoid a
significant conflict; it would align the timezone rule with the
political bodies defining them; and it would reduce overall confusion
for neighboring localities.

I don't know if those are sufficient reason to deviate from Theory,
but I have always felt that the Theory was problematic on this point.
While we may manage the history of timezones based on the times in
particular places, that is not how people think of their time
zone. Unless you happen to live in one of the capital/populous cities
we have designated, people think of their time zone as designated by
their political authority. Having to pick a city that you know is
not-where-you-are is always somewhat of a humbling exercise.
