Python converts the ObjectId in MongoDB to a timestamp method

This article illustrates how python converts ObjectId in MongoDB to a timestamp. Share with you for your reference. Specific analysis is as follows:

The first four bits of the _id field in MongoDB are hexadecimal representations of the timestamp, which can be easily extracted from _id through 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')))

Returns: 1377252547.0

PS: here again for you to recommend a site Unix timestamp conversion tool, with a variety of languages (Python/PHP/ Java /MySQL, etc.) Unix timestamp operation method:

I hope this article has helped you with your Python programming.
