🎲 生成随机时钟时间Generate Random Clock Times

使用说明与常见问题How-to & FAQ

「生成随机时钟时间」是什么？What is the Generate Random Clock Times tool?

随机生成若干 HH:MM:SS（可设种子）。本地处理。可设置「个数」、「种子」。Random HH:MM:SS times (optional seed). Processed locally. Settings: Count, Seed.

如何使用「生成随机时钟时间」？How do I use the Generate Random Clock Times tool?

设置个数和种子，下方即生成随机的 HH:MM:SS 时间；种子留空则每次不同。Set Count and Seed and random HH:MM:SS times appear below; leave Seed empty for different times each run.

时间是怎么分布的？How are the times distributed?

在一天的 86400 秒（00:00:00–23:59:59）中均匀随机抽取。Uniformly over the 86,400 seconds of a day, from 00:00:00 to 23:59:59.

怎样得到可复现的结果？How do I get the same result again?

填写相同的“种子”会得到相同的结果；把种子留空则每次使用浏览器的安全随机数（crypto.getRandomValues），结果每次不同。The same Seed always gives the same result. Leave Seed empty to use the browser's secure random numbers (crypto.getRandomValues), which give a different result each time.

和时区有关吗？Do time zones matter?

无关，这里只处理钟面时间或日历日期，不读取设备时钟，也不考虑夏令时。No. It works on clock readings or calendar dates only, never reads your device clock and ignores daylight saving time.

输入和输出是什么样的？What does the input and output look like?

例如在「生成随机时钟时间」中把「个数」设为 3，「种子」设为 1，输出为：19:57:40 ⏎ 02:57:07 ⏎ 19:49:48（⏎ 表示换行）。For example, in the Generate Random Clock Times tool with "Count" set to 3, "Seed" set to 1, the output is: 19:57:40 ⏎ 02:57:07 ⏎ 19:49:48 (⏎ marks a line break).

有哪些选项可以调整？What options can I adjust?

「生成随机时钟时间」的设置：「个数」默认 5；「种子」默认 1。每次生成结果都按当前设置处理。Settings in the Generate Random Clock Times tool — "Count" default 5; "Seed" default 1. The result always uses the current settings.
