Helpful tip for Brazilian coders in need of timezone information. Here follows the list of timezones used by each state (source: https://en.wikipedia.org/wiki/Time_in_Brazil):

$timezones = array(
'AC' => 'America/Rio_branco',   'AL' => 'America/Maceio',
'AP' => 'America/Belem',        'AM' => 'America/Manaus',
'BA' => 'America/Bahia',        'CE' => 'America/Fortaleza',
'DF' => 'America/Sao_Paulo',    'ES' => 'America/Sao_Paulo',
'GO' => 'America/Sao_Paulo',    'MA' => 'America/Fortaleza',
'MT' => 'America/Cuiaba',       'MS' => 'America/Campo_Grande',
'MG' => 'America/Sao_Paulo',    'PR' => 'America/Sao_Paulo',
'PB' => 'America/Fortaleza',    'PA' => 'America/Belem',
'PE' => 'America/Recife',       'PI' => 'America/Fortaleza',
'RJ' => 'America/Sao_Paulo',    'RN' => 'America/Fortaleza',
'RS' => 'America/Sao_Paulo',    'RO' => 'America/Porto_Velho',
'RR' => 'America/Boa_Vista',    'SC' => 'America/Sao_Paulo',
'SE' => 'America/Maceio',       'SP' => 'America/Sao_Paulo',
'TO' => 'America/Araguaia',    
);

Mirai Densetsu is wrong by saying that "America/Sao_Paulo" timezone does not exist and should be changed to "America/Brasilia".
This list is based on "Time Zone Database", maintained by Internet Assigned Numbers Authority (IANA). The location part of the name, accordingly to the naming convention, uses the "most populous city in a region to represent the entire time zone, although other cities may be selected if they are more widely known or result in a less ambiguous name".
It does not strictly consider local political divisions, because they are subject to change more than names of large cities.

This suggestion does not proceed.

Note that "America" means "the continents of North and South America, including the Caribbean islands".  It does *not* mean "The United States Of America".

If you're looking for the Hawaii timezone, you'll find it in Pacific/Honolulu (not America/Honolulu).

At Brazil, note that the Brazilian official timezone is wrongly described as "America/Sao_Paulo", when it should be "America/Brasilia".

The Sao Paulo timezone does not exist, since this city follow the Brasilia official timezone (BRT or BRST).

I give the folks in the USA the benefit of the doubt in that they know their own time zone and whether or not to use daylight savings time.   The whole city list can be boiled down to just fourteen entries (including Hawaii and Puerto Rico).

<?php

 
//  Timezone suggestions from PHP CookBook By Adam Trachtenberg
  //  and David Sklar Table 3-5 zoneinfo zones

 
$zones = array();
 
$zones['Pacific/Honolulu']     = 'Hawaii-Aleutian Standard Time (HAST)';
 
$zones['US/Aleutian']          = 'Hawaii-Aleutian with Daylight Savings Time (HADT)';
 
$zones['Etc/GMT+9']            = 'Alaska Standard Time (AKST)';
 
$zones['America/Anchorage']    = 'Alaska with Daylight Savings Time (AKDT)';
 
$zones['America/Dawson_Creek'] = 'Pacific Standard Time (PST)';
 
$zones['PST8PDT']              = 'Pacific with Daylight Savings Time (PDT)';
 
$zones['MST']                  = 'Mountain Standard Time (MST)';
 
$zones['MST7MDT']              = 'Mountain with Daylight Savings Time (MDT)';
 
$zones['Canada/Saskatchewan']  = 'Central Standard Time (CST)';
 
$zones['CST6CDT']              = 'Central with Daylight Savings Time (CDT)';
 
$zones['EST']                  = 'Eastern Standard Time (EST)';
 
$zones['EST5EDT']              = 'Eastern with Daylight Savings Time (EDT)';
 
$zones['America/Puerto_Rico']  = 'Atlantic Standard Time (AST)';
 
$zones['America/Halifax']      = 'Atlantic with Daylight Savings Time (ADT)';

You can set a default time zone for your server from the configuration file (php.ini) at the line:

[Date]
; Defines the default timezone used by the date functions
date.timezone = America/New_York
