使用说明与常见问题How-to & FAQ
「分析时钟时间」是什么？What is the Analyze Clock Time tool?
给出 12 小时制、距午夜秒数、时针分针夹角等。本地处理。12-hour form, seconds since midnight, hour/minute hand angle and more. Processed locally.
如何使用「分析时钟时间」？How do I use the Analyze Clock Time tool?
输入 HH:MM 或 HH:MM:SS（24 小时制），下方会显示 12 小时制写法、距午夜的秒数、到下一个午夜的秒数和时针分针夹角。Enter a time as HH:MM or HH:MM:SS on a 24-hour clock to see the 12-hour form, the seconds since midnight, the seconds until the next midnight and the angle between the hour and minute hands.
夹角怎么算？How is the angle worked out?
时针每小时走 30°、每分钟 0.5°、每秒 1/120°；分针每分钟 6°、每秒 0.1°。取两针之间较小的夹角（0–180°），保留 3 位小数，和「计算钟表指针夹角」的“时-分”结果完全一致：13:45:30 是 139.75°。秒针本身不参与这个夹角。The hour hand moves 30° per hour, 0.5° per minute and 1/120° per second; the minute hand moves 6° per minute and 0.1° per second. The smaller angle between them (0–180°) is shown to 3 decimals and matches the Hour-minute result of the Calculate Clock Hand Angle tool exactly — 13:45:30 gives 139.75°. The second hand itself is not part of this angle.
和时区有关吗？Do time zones matter?
无关。时间按你输入的 24 小时制钟面时间计算，页面不读取设备时钟，所以时区和夏令时不影响结果。No. The time is used exactly as typed, as a 24-hour clock reading, and the page never reads your device clock, so time zones and daylight saving time do not affect the result.
