使用说明与常见问题How-to & FAQ
「生成时间序列」是什么？What is the Generate Time Sequence tool?
从起始到结束（含）按固定秒步长生成时间，结束早于开始时跨过午夜。输入两行起止时间，选项为步长秒。本地处理。Times from start to end (inclusive) with a fixed step in seconds; an end before the start crosses midnight. Two lines + step. Processed locally.
如何使用「生成时间序列」？How do I use the Generate Time Sequence tool?
第一行输入开始时间、第二行输入结束时间，设置步长秒，下方即生成时间序列。Enter the start time on the first line and the end time on the second, set the step in seconds, and the sequence appears below.
结束早于开始会怎样？What if the end is before the start?
视为跨过午夜，例如 23:59 到 00:01 得到 23:59:00、00:00:00、00:01:00，并提示后面的时间属于第二天。The sequence crosses midnight; for example 23:59 to 00:01 gives 23:59:00, 00:00:00 and 00:01:00, with a note that the later times are on the next day.
最多显示多少个？How many times are shown?
最多显示前 500 个；超过时会显示前 500 个并提示总数。步长留空按 60 秒计算。At most the first 500; if there are more, the first 500 are shown with a note giving the total. An empty step counts as 60 seconds.
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?
例如把「步长秒」设为 60，输入 12:00:00 ⏎ 12:02:00，输出为：12:00:00 ⏎ 12:01:00 ⏎ 12:02:00（⏎ 表示换行）。With "Step seconds" set to 60, the input 12:00:00 ⏎ 12:02:00 becomes 12:00:00 ⏎ 12:01:00 ⏎ 12:02:00 (⏎ marks a line break).
有哪些选项可以调整？What options can I adjust?
「生成时间序列」的设置：「步长秒」默认 60。每次生成结果都按当前设置处理。Settings in the Generate Time Sequence tool — "Step seconds" default 60. The result always uses the current settings.
