[tz] Samoa Standard Time

FYI:  I sent the following message to my U.S. Senators and my U.S. Representative:

Whereas there exists a country which has been named Samoa since July 1997,

Whereas Samoa is entirely separate from the Territory of American Samoa,

Whereas Samoa and American Samoa have had standard times since 1911,

Whereas the standard time in Samoa has differed from the standard time in American Samoa since the 30th of December 2011 (in addition to the period from 1911 to 1950, when the time in Western Samoa was known as Samoa Time and the time in American Samoa was known as Nome Standard Time), and

Whereas the standard times in both locations continue to be known as Samoa Standard Time,

 

Despite the report in the Samoa Wikipedia article that American Samoans protested Samoa's name change and continue to call it Western Samoa, and

Despite the difference between the abbreviations of Samoa's Samoa Standard Time (WSST) and American Samoa's Samoa Standard Time (SST), which is due to the fact that the ISO-3166 international standard abbreviation of Samoa is still WS,

 

In the interest of reducing international confusion, I recommend that the Code of Federal Regulations, Title 49, Subtitle A, Part 71, Section 71.13 and the United States Code, Title 15, Chapter 6, Subchapter IX, Section 263 be amended to change the name of the standard time in American Samoa from Samoa standard time to American Samoa standard time.

 

Although I hope they make the change, I’m not holding my breath.  I sent a similar message last year to the U.S. Department of Transportation, the Executive Department in charge of U.S. time zones, but received no reply.  Besides, if we were interested in reducing international confusion, we would have switched to the metric system.

[tz] Hawaii-Aleutian Standard Time

I happened to notice that the U.S. Code of Federal Regulations, Title 49, Subtitle A, Part 71, Section 71.12 states “...the Hawaii-Aleutian standard time zone, includes the entire State of Hawaii and, in the State of Alaska, that part of the Aleutian Islands that is west of 169 degrees 30 minutes west longitude.”

The America/Adak Zone data include this change, but the Pacific/Honolulu Zone data do not.

[tz] Yukon time history updates with references containing some Canadian and global data

It seemed unlikely to me that the statement about the Yukon in line 1844 below "This is still valid;" was
still valid, except in the sense that Yukon standard time may still be defined as GMT-9, although standard
time in Yukon has not had that offset, and the name has not been used with that meaning, except in some
historical sense, since 1973.
So I tried to trace the history of Yukon time and found the following regulations, giving the reference
title and URL if found, regulation name, and relevant quote if available.
Each regulation specifically revokes its predecessor.
The final reference is to the current Interpretation Act authorizing and resulting from these regulatory changes.

Only recent regulations were retrievable via Yukon government site search or index, and only some via
Canadian legal sources. Other sources used include articles titled "Standard Time and Time Zones in
Canada" from JRASC via ADS Abstracts, cited by ADO for 1932 in northamerica:1456, and updated versions
from 1958 and 1970 quoted below; each article includes current extracts from provincial and territorial
ST and DST regulations at the end, summaries and details of standard times and daylight saving time at many
locations across Canada, with time zone maps, tables and calculations for Canadian Sunrise, Sunset, and
LMST; they also cover many countries and global locations, with a chart and table showing current
Universal Time offsets, and may be useful as another source of information for 19
 70 and earlier.

The coordinator should decide how much Yukon time history should change, relative to that currently
documented at:

[tz] [tz-announce] 2015c release of tz code and data available

The 2015c release of the tz code and data is available.  It reflects the 
following changes, which were either circulated on the tz mailing list or are 
relatively minor technical or administrative changes.  Although this release is 
based on the best information we had when it was made, the daylight-saving 
situation in Egypt seems to be fluid, and we may need to generate another 
release soon.

   Changes affecting future time stamps

     Egypt's spring-forward transition is at 24:00 on April's last Thursday,
     not 00:00 on April's last Friday.  2015's transition will therefore be on
     Thursday, April 30 at 24:00, not Friday, April 24 at 00:00.  Similar fixes
     apply to 2026, 2037, 2043, etc.  (Thanks to Steffen Thorsen.)

   Changes affecting past time stamps

     The following changes affect some pre-1991 Chile-related time stamps
     in America/Santiago, Antarctica/Palmer, and Pacific/Easter.

       The 1910 transition was January 10, not January 1.

       The 1918 transition was September 10, not September 1.

       The UTC-4 time observed from 1932 to 1942 is now considered to be
       standard time, not year-round DST.

       Santiago observed DST (UTC-3) from 1946-07-15 through 1946-08-31,
       then reverted to standard time, then switched its time zone to
       UTC-5 on 1947-04-01.

       Assume transitions before 1968 were at 00:00, since we have no data
       saying otherwise.

       The spring 1988 transition was 1988-10-09, not 1988-10-02.
       The fall 1990 transition was 1990-03-11, not 1990-03-18.

       Assume no UTC offset change for Pacific/Easter on 1890-01-01,
       and omit all transitions on Pacific/Easter from 1942 through 1946
       since we have no data suggesting that they existed.

     One more zone has been turned into a link, as it differed
     from an existing zone only for older time stamps.  As usual,
     this change affects UTC offsets in pre-1970 time stamps only.
     The zone's old contents have been moved to the 'backzone' file.
     The affected zone is America/Montreal.

   Changes affecting commentary

     Mention the TZUpdater tool.

     Mention "The Time Now".  (Thanks to Brandon Ramsey.)

[tz] TZ for Egypt Change

Good day,

 

According to several news reports, Egypt will start DST on midnight after

Thursday, April 30, 2015.

This is based on a law (no 35) from May 15, 2014 saying it starts the

last Thursday of April.

This means we will to change the rule to "lastThu 24:00s" instead of

"lastFri 0:00s". Clocks will still be turned back for Ramadan, but dates not  yet announced.

[tz] Leap seconds puzzle

Gentlepeople,

I’ve been sorting to a flurry of questions about leap seconds from colleagues (triggered by the recent
announcement of an upcoming leap second).  That sent me to the Theory file, and some experiments.  Those
experiments leave me puzzled.

I apologize for going a bit off topic for this list, but the expertise is clearly here.

The Theory file says that POSIX requires leap seconds to be ignored.  And indeed, if I set my system timezone
to a POSIX zone description and ask it to convert a time value that’s an integer multiple of 86400, I end up
at an exact hour (or half hour) multiple, for example exactly midnight if UTC.  And similarly, if I set my
zone to a “right” one and do the conversion, I get a time that’s a few seconds shy of the exact
multiple, as expected.

I can also see that my default timezone definitions on my various Unix machines are POSIX ones, again as expected.

So here is the puzzle.  I would expect WWV, and www.time.gov, to reflect leap seconds.  So why would they give
me a time that matches, to the second, the POSIX time on my workstation?  Does NTP send POSIX seconds since
epoch rather than real ones?

[tz] Liberal and conservative time zones in 1950s Nashville

In 1950s Nashville a public clock had dueling faces, one for conservatives and 
the other for liberals; the two sides didn't agree about the time of day. I 
haven't found a photo of this clock, nor have I tracked down the TIME magazine 
report cited below, but here's the story as told by the late American journalist 
John Seigenthaler, who was there:

"The two [newspaper] owners held strongly contrasting political and ideological 
views. Evans was a New South liberal, Stahlman an Old South conservative, and 
their two papers frequently clashed editorially, often on the same day.... In 
the 1950s as the state legislature was grappling with the question of whether to 
approve daylight saving time for the entire state, TIME magazine reported:

"'The Nashville Banner and The Nashville Tennessean rarely agree on anything but 
the time of day — and last week they couldn't agree on that.'

"It was all too true. The clock on the front of the building had two faces — The 
Tennessean side of the building facing west, the other, east. When it was high 
noon Banner time, it was 11 a.m. Tennessean time."

My source:

Seigenthaler J. For 100 years, Tennessean had it covered. The Tennessean
