Unix 时间戳转换器 Unix Timestamp Converter
Unix 秒/毫秒 ↔ 日期时间,支持本地时间与 UTC,并支持批量转换。
Convert Unix seconds/milliseconds ↔ DateTime (Local & UTC) with batch conversion.
1. 输入参数 · Inputs
3. 批量转换 · Batch Convert
批量模式会逐行尝试解析:
1)纯数字 → 当作 Unix 时间戳(秒/毫秒自动识别或按规则推断)。
2)带
3)形如
Batch parser tries per line:
(1) digits → Unix timestamp (auto detect s/ms).
(2) ISO with timezone (Z / +08:00) → parsed as absolute time.
(3) “YYYY-MM-DD HH:mm:ss” → treated as Local time.
输出里无法解析的行会标注为 ERR,不影响其它行。
Unparsable lines are marked as ERR, others continue.

常用用途:日志对齐、接口调试、数据库排查、量化交易数据时间字段核对。
Typical use cases: log alignment, API debugging, DB troubleshooting, trading/quant timestamp checks.

4. 使用说明 · Notes
-
秒 vs 毫秒(最容易踩坑) · Seconds vs Milliseconds (most common pitfall):
很多后端/数据库使用 秒(10 位),而 JavaScript/前端埋点常用 毫秒(13 位)。
Many backends/DBs use seconds (10 digits), while JS/frontend events often use milliseconds (13 digits).
如果你转换出来的日期跑到了 1970 年附近或遥远未来,十有八九是单位选错了。
If the result lands near 1970 or far in the future, you likely picked the wrong unit. -
本地时间 vs UTC(第二大坑) · Local vs UTC (second biggest pitfall):
UTC 是统一时间标准;本地时间 会随着你电脑所在时区变化。
UTC is a universal reference; Local depends on your device timezone.
同一个 Unix 时间戳,在不同地区显示的“本地时间”会不同,但 UTC 是一致的。
The same Unix timestamp shows different local times across regions, but UTC remains consistent. -
为什么 datetime-local 不带时区? · Why does datetime-local have no timezone?
它只是一串“年月日时分”的输入控件,不携带时区信息,所以你必须选择“按本地解释/按 UTC 解释”。
It is just a plain date-time input without timezone info — that’s why you must choose how to interpret it. -
批量转换的推荐格式 · Recommended batch formats:
✅ Unix:1700000000/1700000000000
✅ ISO:2025-12-16T12:30:00Z(带 Z = UTC,最稳定)
✅ 本地文本:2025-12-16 20:30:00(默认按本地解析)
推荐你在跨系统/跨地区沟通时优先使用 ISO + Z,减少歧义。
Prefer ISO with Z when working across systems/regions to avoid ambiguity. -
精度提示 · Precision note:
Unix 秒只能到“秒级”,Unix 毫秒可到“毫秒级”。如果你只存秒,毫秒会被截断。
Seconds are only second-precision; milliseconds keep ms-precision. If you store only seconds, ms will be truncated.
