如何将Date对象传递给mongo数据库，传递mongo数据库后转换为Int64。如何使用pymongo做到这一点

import pymongo

client = pymongo.MongoClient("mongodb://localhost:27017/")

db = client["mydatabase"]

collection = db["mycollection"]

import datetime
date = datetime.datetime.now()

result = collection.insert_one({"date": date})

import bson
int64_date = bson.Int64(date.timestamp() * 1000)

client = pymongo.MongoClient("mongodb://localhost:27017/")

collection = db["mycollection"]

date = datetime.datetime.now()

int64_date = bson.Int64(date.timestamp() * 1000)
