Contoh

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

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.
