當你在 Azure 使用 App Service 部署網站時，預設的時區是設定在 UTC 時間，當你的網站不需要處理跨時區的問題時，最簡單的解法，當然就是調整系統設定，讓你的程式可以直接讀取到台灣時區的時間 (UTC+8)，原本我們都設定的好好的，但上周突然決定要改用以 Linux 為主的 App Service Plan，這才發現時區設定失效了，查詢後才發現原來設定不同！這篇文章我將說明如何正確的調整 App Service 的時區設定。
在 Windows 變更時區的方法
如果你今天執行的是一台 VM 或是本機 Windows 電腦，在 Windows 作業系統中預設內建一個 tzutil 工具，可以幫助你列出完整的可用時區列表與時區名稱，使用方式如下：
tzutil /l

台灣這邊的時區名稱為 Taipei Standard Time (台北標準時間)，所以如果要用命令列去設定目前使用的時區，可以這樣執行：
tzutil /s "Taipei Standard Time"
取得目前時區的命令為：
tzutil /g
在 App Service on Windows 變更時區的方法
你只要在 App Service 的 應用程式設定 (Application settings) 加入一個 WEBSITE_TIME_ZONE 組態，並且將值設定正確就可以調整完成。
這裡你必須使用 tzutil /l 列出的可用時區名稱，台灣這邊的時區就是 Taipei Standard Time！
以下是透過 Azure CLI 設定時區的方法：
az webapp config appsettings set -g '資源群組名稱' -n '資源名稱' --settings 'WEBSITE_TIME_ZONE=Taipei Standard Time'
以下是透過 Azure CLI 刪除時區設定的方法：
az webapp config appsettings set -g '資源群組名稱' -n '資源名稱' --setting-names 'WEBSITE_TIME_ZONE'
在 App Service on Linux 變更時區的方法
你只要在 App Service 的 應用程式設定 (Application settings) 加入一個 TZ 組態，並且將值設定正確就可以調整完成。
這裡你必須從 List of tz database time zones 查到 TZ database name (時區資料庫名稱) 來當成 Linux 下可用的時區名稱，這部分跟 App Service on Windows 不太一樣，有點雷，真的遇到才知道。，台灣這邊的時區就是 Asia/Taipei！
如果你手邊有 Linux 可以用，是可以透過以下命令找出時區資料庫的名稱清單：
timedatectl list-timezones
timedatectl list-timezones | grep Taipei
以下所全部列出，方便大家直接搜尋：
