What is this
什么是 Unix 时间戳
Unix 时间戳是从 1970-01-01 00:00:00 UTC 起经过的秒数（或毫秒数），是日志、数据库与 API 最常用的时间表示。本工具支持双向转换与实时「当前时间」时钟。
What is a Unix timestamp
A Unix timestamp counts seconds (or milliseconds) since 1970-01-01 00:00:00 UTC — the standard time representation in logs, databases and APIs. This tool converts both ways and shows a live “now” clock.
如何使用
- 粘贴时间戳自动转换，或粘贴日期字符串反向生成时间戳。
- 位数自动识别（10 位秒 / 13 位毫秒）。
- 结果同时给出本地时区与 UTC 两种可读格式。
FAQ
10-digit vs 13-digit timestamps?
10 digits = seconds, 13 digits = milliseconds. Detection is automatic, with a manual override.
Which timezone is shown?
Your device's local timezone by default, plus the UTC equivalent for reference.
Will Unix time overflow?
32-bit second timestamps overflow in 2038; 64-bit systems and millisecond timestamps are unaffected.
