Python converts the Objectid in MongoDB into a timestamp method

This example describes how Python converts objectid in MongoDB into a timestamp. Share to everyone for your reference. The specific analysis is as follows:

The first four bits of the _id field in MongoDB are 16 binary representations of timestamps, and it is easy to extract timestamps from _id by 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 we recommend a local UNIX timestamp conversion tool, with various languages (PYTHON/PHP/JAVA/MYSQL, etc.) Unix timestamp operation method:

Hopefully this article will help you with Python programming.
