[tz] U.S. Pacific Time

[Alan Mintz]

...and here's my report from 2012-05-21:

I see someone tried to address this last month but it kind of fell flat. 
The solution seems clear to me, as described here:


>In ftp://ftp.iana.org/tz/data/northamerica v8.54 dated 2009-05-17 (the 
>current version), it says"
>
># US Pacific time, represented by Los Angeles
>#
># California, northern Idaho (Benewah, Bonner, Boundary, Clearwater,
># Idaho, Kootenai, Latah, Lewis, Nez Perce, and Shoshone counties,
># and the northern three-quarters of Idaho county),
># most of Nevada, most of Oregon, and Washington
>
>The first instance of Idaho in the county list (between Clearwater and 
>Kootenai) should be removed since the list ends with "and the northern 
>three-quarters of Idaho county". That is, only the northern 3/4 of the 
>county, not the whole county, is included (assuming that is true).


The dividing line is actually the Salmon River, so I would change the 
paragraph to:

# US Pacific time, represented by Los Angeles
#
# California, northern Idaho (Benewah, Bonner, Boundary, Clearwater,
# Kootenai, Latah, Lewis, Nez Perce, and Shoshone counties,
# and the part of Idaho county lying north of the Salmon River),
# most of Nevada, most of Oregon, and Washington

If we wanted to give the same detail treatment to NV and OR:

# US Pacific time, represented by Los Angeles
#
# - California
# - Washington
# - Northern Idaho (Benewah, Bonner, Boundary, Clearwater,
# Kootenai, Latah, Lewis, Nez Perce, and Shoshone counties,
# and the part of Idaho county lying north of the Salmon River)
# - Oregon (except for the northern 3/4 of Malheur County)
# - Nevada (except for West Wendover)


...and again on 2012-06-08:

I'd like to try this once more without it getting buried or expanded into 
other issues, please.

As it's written, the America/Los_Angeles comment in northamerica v8.54 in 
tzdata release 2012c does not make sense. The simple solution is to remove 
7 characters from line 395:

< northamerica
 > northamerica.new

395c395
< # Kootenai, Latah, Lewis, Nez Perce, and Shoshone counties,
---
 > # Idaho, Kootenai, Latah, Lewis, Nez Perce, and Shoshone counties,


Alternatively, more accuracy could be provided by the following changes:

< northamerica
 > northamerica.new

395,397c395,398
< # Idaho, Kootenai, Latah, Lewis, Nez Perce, and Shoshone counties,
< # and the northern three-quarters of Idaho county),
< # most of Nevada, most of Oregon, and Washington
---
 > # Kootenai, Latah, Lewis, Nez Perce, and Shoshone counties,
 > # the towns of Burgdorf and Warren, and the part of Idaho county
 > # lying north of the Salmon River), Nevada (except for West Wendover)
 > # Oregon (except for part of Malheur County), and Washington


AFAIK, this description is completely accurate (though it doesn't reflect 
unofficial observances in Nevada, which I assume wouldn't be appropriate here).

(see http://mm.icann.org/pipermail/tz/2012-June/018083.html for ensuing 
discussion, which went off on a fine point about Oregon and died).
