📌 适用场景

Unix 时间戳是系统记录时间的标准方式。本工具支持秒 / 毫秒时间戳与日期互转，显示 UTC 与本地时间，方便排查日志时间、接口时区问题，适合后端调试与跨时区协作。

📖 深入了解 Timestamp Converter — Unix Epoch to Date & Time

为什么需要它

跨制式沟通不再卡壳
烹饪、装修、学习时即时换算
避免记错系数导致的错误

背后的原理

Timestamp Converter — Unix Epoch to Date & Time 基于单位间的固定换算系数做线性映射，输入一个值即得其他单位的等价量。要注意十进制与二进制系数不同（如存储单位），以及公制与英制的差异。

一个例子

例如把 1 个常用单位输入 Timestamp Converter — Unix Epoch to Date & Time，立刻看到其他单位的等价量；切换公制/英制时数值自动重算，无需手算系数。

常见误区

混淆十进制与二进制单位（如 KB 与 KiB）
忽略英制与公制的换算系数
把近似换算当作精确值使用

⏱️ Timestamp Converter

Convert Unix timestamps (epoch) to readable dates and back. Supports seconds and milliseconds, shows both UTC and your local time.

📋 How to Use

The "Current Unix Time" box shows the live epoch value (updated every second).
Paste a timestamp and pick seconds or milliseconds to see it as a date.
Pick a date/time with the picker (or "Use Now") to get its Unix value.
Copy any result with a click — results are plain text.

❓ FAQ

What is a Unix timestamp?

A Unix timestamp is the number of seconds (or milliseconds) elapsed since midnight UTC on January 1, 1970 (the "epoch"). It's a universal, timezone-free way to store time.

Seconds or milliseconds?

Many systems use seconds (10 digits, e.g. 1753216800). JavaScript and some APIs use milliseconds (13 digits). Use the dropdown to match your source.

Why do UTC and local time differ?

UTC is timezone-independent. "Your Local Time" is converted using your device's timezone setting, so it may differ from UTC by several hours.

时间戳是什么？

通常指 Unix 时间戳，是从 1970-01-01 00:00:00 UTC 起经过的秒数（或毫秒数）。

时区怎么处理？

时间戳本身是时区无关的；本工具可在 UTC 和你的本地时间之间双向转换。

转换需要联网吗？

不需要。时间换算完全在浏览器本地进行。
