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).

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).

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

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)';
