可以选哪些时区？夏令时怎么处理？Which time zones can I choose, and how is daylight saving handled?
下拉框顶部是常用城市，下面是浏览器支持的全部 IANA 时区；也可以在搜索框里输入城市或时区名（如 Kathmandu、Asia/Kathmandu）快速定位。夏令时按浏览器内置的时区数据库计算：夏令时开始时不存在的时刻会顺延，结束时重复出现的时刻按较早的一次计算，并会给出提示。Popular cities are at the top of each list, followed by every IANA time zone your browser supports; you can also type a city or zone name (such as Kathmandu or Asia/Kathmandu) in the search box. Daylight saving uses the browser's built-in time zone database: a time skipped when clocks go forward is moved past the gap, and a repeated time when clocks go back uses the earlier one, with a note.
