Python converts the Objectid in MongoDB to the timestamp method _python

This article illustrates the way Python converts objectid in MongoDB to timestamps. Share to everyone for your reference. The specific analysis is as follows:

The first four bits of the _id field in MongoDB are the 16-bit timestamp, which makes it easy to extract the timestamp from the _id by using Python

def timestamp_from_objectid (objectid): Result
 = 0
 Try: Result
  = Time.mktime (objectid.generation_ Time.timetuple ())
 except: Pass return result
 

Call Method:

Print (Timestamp_from_objectid objectid (' 5217a543dd99a6d9e0f74702 '))

return: 1377252547.0

PS: Here again for you to recommend a local UNIX timestamp conversion tool, with a variety of languages (python/php/java/mysql, etc.) Unix timestamp operation methods:

I hope this article will help you with your Python programming.
