West Falkland time zone

Dear All,

	Here's a reference to the lack of daylight savings time use in the  
West Falklands.

Thanks.  I suppose we should have a separate entry for this.
But I'm not sure what location we should use.  In your 2001-02-13 email you wrote:

  Also, there is no mention in the list that some areas in the
  Falklands do not use DST.  I have found in my communications there
  that these areas are on the western half of East Falkland and all of
  West Falkland.  Stanley is the only place that consistently observes
  DST.  Again, as in other places in the world, the farmers don't like
  it.  West Falkland is almost entirely sheep farmers.

Our usual rule is to use the most populous location in the area, but
the boundaries of this area seem to be fairly vague.  Perhaps Port
Howard would be best?  (Or maybe Goose Green? but it might flip-flop.)

Part of the problem is that I don't have good figures for populations
of these small towns.  www.world-gazetteer.com estimates 80 for Goose
Green, 39 for Port Howard, and 22 for Grytviken, but that's it (other
than Port Stanley of course).

Iraq sprang forward twice this weekend

The AP reported today that the Iraqi government issued a statement two
weeks ago saying DST would begin yesterday (March 31) at 00:00 local
time.  At the appointed time the American military obediently shifted
its clocks forward, but state-run TV did not.  Apparently the cabinet
had changed its mind, without notifying the Americans.  State-run TV
later announced that the government had decided to change the time
today at 00:00 local time instead.

No changes are needed to the tz database for this one, since it agrees
with what the Iraqis eventually ended up with.  We were lucky that we
didn't get that statement two weeks ago.

Here's a reference:

Question on interpretation of rules intervals

Hi all,

I have a question about how to interpret the US set of rules. After 
going through the "zic" man page and the mailing list archive I am still 
unclear about the meaning of using this:

[...]
Rule US 1942 only - Feb  9 2:00   1:00 W # War
Rule US 1945 only - Aug 14 23:00u 1:00 P # Peace
Rule US 1945 only - Sep 30 2:00      0 S
[...]

in a zone definition like this:

Zone America/New_York -4:56:02 -  LMT  1883 Nov 18 12:03:58
                       -5:00   US  E%sT 1920
                       -5:00   NYC E%sT 1942
                       -5:00   US  E%sT 1946
                       [...]

As I see it, the US rule has a transition in 1942 (only), on Feb 9th, 
where it saved 1 hour. Am I correct in interpreting the gap of 43-44 as:

1. The transition of 1942 was observed up until 1945, Sep 30th, and...
2. The entry for Aug 14th, 1945 transition exists only in order to be
    used in time zones which did not observe the 1942 transition?

Thanks,
Liviu

RE: Question on interpretation of rules intervals

Starting in 1942, the U.S. observed Daylight Saving Time year-round as
part of a war-time effort to conserve energy; rather than being called
"Standard" or "Daylight" time, it was called "War" time (as in "Eastern
War Time").

WWII ended during the summer of 1945, when Daylight Saving Time would
normally be observed; folks started using "Peace" rather than "War" in
time zone names (such as "Eastern Peace Time").

When the normal "fall back" date arrived in 1945, folks reverted to
"Eastern Standard Time" (and to "Eastern Daylight Time" in 1946).

So...there's one rule in 1942 to get things on to "War" time (in effect
through 1945, with no clock changes), one rule in 1945 to get things on
to "Peace" time, and one rule in 1945 to "fall back" to standard time.

RE: Question on interpretation of rules intervals

Here's how I interpret it:

"War Time" (1 hour advanced) stayed in effect from Feb 9, 1942, through
1943 and 1944 and into 1945.  On August 14, 1945, the name (only)
changed from "War Time" to "Peace Time", since hostilities had ended.
The time was still one hour advanced.  This continued until September
30, 1945, when Standard Time resumed.
