⏱ 生成 Unix 时间戳序列Generate Unix Time Sequence
从起始到结束按步长生成 Unix 秒序列（结束小于起始时倒序）。输入两行起止，选项为步长。本地处理。可设置「步长」。Unix second sequence from start to end with a step (descending when the end is smaller). Processed locally. Settings: Step.
使用说明与常见问题How-to & FAQ
「生成 Unix 时间戳序列」是什么？What is the Generate Unix Time Sequence tool?
从起始到结束按步长生成 Unix 秒序列（结束小于起始时倒序）。输入两行起止，选项为步长。本地处理。可设置「步长」。Unix second sequence from start to end with a step (descending when the end is smaller). Processed locally. Settings: Step.
如何使用「生成 Unix 时间戳序列」？How do I use the Generate Unix Time Sequence tool?
第一行输入起始时间戳、第二行输入结束时间戳，设置步长，下方即生成时间戳序列。Enter the start timestamp on the first line and the end timestamp on the second, set Step, and the sequence appears below.
结果太多时会怎样？What if there are too many values?
最多显示前 500 个，并提示总共有多少个；数量会先算出来，所以再大的范围也会立即返回。Only the first 500 are shown, with a note giving the total. The count is worked out first, so even a huge range returns instantly.
可以输入哪些数？What values can I enter?
十进制整数秒，可带负号，范围 ±9007199254740991（±2^53-1）；步长为 1–1000000000，留空按 1 计算。结束小于起始时倒序生成。Whole decimal numbers of seconds, optionally negative, from -9007199254740991 to 9007199254740991 (±2^53-1). The step is 1 to 1,000,000,000 and counts as 1 when empty. When the end is smaller than the start the values count down.
Unix 时间戳和时区有关吗？Do time zones affect Unix timestamps?
无关。Unix 时间戳是自 1970-01-01 00:00:00 UTC 起的秒数，本身不带时区；本工具只处理这些整数，不读取设备时区。No. A Unix timestamp counts seconds since 1970-01-01 00:00:00 UTC and has no time zone of its own; this tool only works with those whole numbers and never reads your device time zone.
输入和输出是什么样的？What does the input and output look like?
例如把「步长」设为 2，输入 0 ⏎ 4，输出为：0 ⏎ 2 ⏎ 4（⏎ 表示换行）。With "Step" set to 2, the input 0 ⏎ 4 becomes 0 ⏎ 2 ⏎ 4 (⏎ marks a line break).
有哪些选项可以调整？What options can I adjust?
「生成 Unix 时间戳序列」的设置：「步长」默认 1。每次生成结果都按当前设置处理。Settings in the Generate Unix Time Sequence tool — "Step" default 1. The result always uses the current settings.
「生成 Unix 时间戳序列」免费吗？需要注册吗？Is the Generate Unix Time Sequence tool free? Do I need an account?
