Civil-time rules change, daylight-saving transitions can repeat or skip local clock readings, and the rules for a place are not captured by labels such as UTC+7 or UTC-5.</p> <p>Python 3.9 added <code>zoneinfo</code> to the standard library to provide IANA time-zone support through the familiar <code>datetime</code> API. It is the right starting point when an application needs rules for named zones such as <code>Asia/Jakarta</code>, <code>Europe/Berlin</code>, or <code>America/New_York</code>.</p>
