MongoDB ObjectId 解碼器：快速上手指南

使用方法

1. 開啟工具，將內容貼上到左側輸入框。
2. 只調整任務真正需要的選項——多數情況下預設值就是正確的。
3. 在右側檢視結果，輸入時結果會即時更新。
4. 用「複製」取走結果，或用「下載」儲存為檔案。

範例

The first four bytes are a Unix timestamp, which is why ObjectIds sort roughly by creation time.

輸入

507f1f77bcf86cd799439011

輸出 — 搜尋結果

507f1f77bcf86cd799439011

Layout (12 bytes / 24 hex characters)
  timestamp    4 bytes  507f1f77  = 1350508407
  random       5 bytes  bcf86cd799   (process-unique, per the current spec)
  counter      3 bytes  439011   = 4427793

Creation time (UTC)   2012-10-17T21:13:27.000Z
Creation time (local) Wed Oct 17 2012 21:13:27 GMT+0000 (Coordinated Universal Time)
Age                   5091.9 days

Older drivers used 3-byte machine id + 2-byte process id instead of 5 random bytes;
both layouts put the timestamp first, which is why ObjectIds sort roughly by time.

執行

說明

Extract the creation timestamp, random bytes and counter from a 24-character ObjectId.
