PHP 開發筆記 - 關於 DST 日光節約時間的判斷邏輯與實現方式

這是一個很古老的議題，但因為產品要進行本地化資訊顯示開始提供一些架構，然而，這本身顯示時間上都已經很成熟也有內建 library 可用，但基於一些嵌入式產品的條件，如連網狀態等，需要復刻一版服務出來，像是把日光節約時間的邏輯給列出來等。

輕鬆問問 Claude.AI 就立馬有了一版，且過程中還發現 AI 採用每日檢查是否是日光節約時間 XD 但明明可以查 tzdata 有效率做完這件事才對。就順手引導 AI ，自己也下去改一下判斷邏輯。

此外，也透過 AI 補足了一些知識，像是 tzdata 會定期更新，且一年也可能更新數次：

data.iana.org/time-zones/releases/

隨便下載一份解開來看：

• zone.tab: 全部時區清單，內有 geo location 資訊
• northamerica: 北美洲的 DST 規則
• europe: 歐洲的 DST 規則
• asia: 亞洲的 DST 規則
• australasia: 澳洲和亞洲部分地區的 DST 規則
• africa: 非洲的 DST 規則
• southamerica: 南美洲的 DST 規則
• antarctica: 南極洲的 DST 規則

而 abbreviation 縮寫意義：

• EST = Eastern Standard Time （東部標準時間）
• EDT = Eastern Daylight Time （東部夏令時間）
• PST = Pacific Standard Time （太平洋標準時間）
• PDT = Pacific Daylight Time （太平洋夏令時間）
• CST = Central Standard Time （中部標準時間）
• CDT = Central Daylight Time （中部夏令時間）

最後，用 PHP Code 順一個出來，這邊 dst_begin 不是日光節約時間真正的起始日，僅是一個趨近資料，只有當該時區不是日光節約時間時，才會是下一個日光節約時段開始的時間

```

<?php

$output = [];

$dst_query_start = strtotime("-7 day midnight");

$days_in_year = date('L') ? 366 + 7 : 365 + 7; // 檢查是否為閏年

$dst_query_end = $dst_query_start + (86400 * $days_in_year);

try {

foreach(DateTimeZone::listIdentifiers() as $tz) {

$datetime = new DateTime('now', new DateTimeZone($tz));

$timezone = new DateTimeZone($tz);

$location = $timezone->getLocation();

$transitions = $timezone->getTransitions($dst_query_start, $dst_query_end);

$has_dst = false;

$dst_begin = array( 'datetime' => NULL, 'timestamp' => NULL, 'offset' => NULL, 'abbreviation' => NULL);

$dst_end = array( 'datetime' => NULL, 'timestamp' => NULL, 'offset' => NULL, 'abbreviation' => NULL);

for ($i=0, $cnt=count($transitions) ; $i < $cnt ; ++$i ) {

if ($has_dst == false) {

if ($transitions[$i]['isdst']) {

$has_dst = true;

$dst_begin = array(

'datetime' => date('Y-m-d H:i:s', $transitions[$i]['ts']),

'timestamp' => $transitions[$i]['ts'],

'offset' => $transitions[$i]['offset'],

'abbreviation' => $transitions[$i]['abbr'],

);

}

} else if (!$transitions[$i]['isdst']) {

$dst_end = array(

'datetime' => date('Y-m-d H:i:s', $transitions[$i]['ts']),

'timestamp' => $transitions[$i]['ts'],

'offset' => $transitions[$i]['offset'],

'abbreviation' => $transitions[$i]['abbr'],

);

break;

}

}

array_push($output, array(

'timezone' => $tz,

'offset' => $datetime->format('P'),

'abbreviation' => $datetime->format('T'),

'is_dst' => (bool)$datetime->format('I'),

'dst_info' => array(

'begin' => $dst_begin,

'end' => $dst_end,

'has_dst' => $has_dst,

),

'country_code' => isset($location['country_code']) && $location['country_code'] != '??' ? $location['country_code'] : null,

'latitude' => isset($location['latitude']) ? $location['latitude'] : null,

'longitude' => isset($location['longitude']) ? $location['longitude']: null,

));

}

} catch (Exception $e) {

$output = $e->getMessage();

}

echo json_encode($output, JSON_PRETTY_PRINT)."\n";

```

在此刻 2024-12-04 運行 PHP Code 結果，透過 jq 來過濾清單，列出哪些有日光節約時段時區：

```

% php83 test.php | jq '[.[] | select(.dst_info.has_dst == true) | {timezone: .timezone, dst_begin: .dst_info.begin.datetime, dst_end: .dst_info.end.datetime}]'
