本頁說明 Android 時區更新政策,並提供政府機關相關建議,確保 Android 裝置盡早更新時區資訊。
Android 時區更新政策
Android 會使用 IANA 機構的時區資料庫、地理區域,以及 Unicode 國際元件 (ICU) 提供的翻譯內容,做為 Android 時區更新的來源。如要進一步瞭解時區更新的運作方式,請參閱「時區更新」。
如要詳細瞭解 Android 裝置的時間和時區運作方式,請參閱時間總覽。
給政府的建議
政府決定變更時區規則後,系統需要一段時間準備並將時區更新傳送至 Android 裝置。為盡量減少對民眾、裝置和系統的潛在影響,建議政府採取下列行動:
- 時區規則變更至少要提前六個月通知。
- 如要通知民眾和公司 (例如電信和航空公司),請在可信的政府網站上發布時區規則異動公告,並在 IANA 郵寄清單中新增貼文,附上公告連結。
- 請務必在公告中清楚說明規則變更內容、受規則變更影響的民事或地理區域,以及變更生效時間。

For more information\nabout how time zone updates work, see [Time zone updates](/docs/core/permissions/timezone-rules#timezone-apex).\n\nFor detailed information on how time and time zones work on Android, see [Time\noverview](/docs/core/connect/time).\n\nRecommendations for governments\n\nIt takes time to prepare and deliver time zone updates to Android devices after\na government decides on a time zone rule change. To minimize the potential\nimpact on citizens, devices, and systems, we recommend governments do the\nfollowing:\n\n- Provide at least six months notice for time zone rule changes.\n- To inform citizens and companies (for example, telecoms and airlines), publish an announcement about time zone rule changes on a credible government website and add a post on the [IANA mailing list](https://mm.icann.org/pipermail/tz/) with a link to the announcement.\n- Ensure that announcements clearly state what the rule change is, the complete and unambiguous details of the civil or geographical regions affected by the rule change, and when the change comes into effect."]]
