from pymongo import MongoClient
cli = MongoClient()
db = cli['test']
tbl = db['test_timer2']
tbl.create_index([("timer2", 1)], expireAfterSeconds=10)
from datetime import datetime
tbl.insert({"timer2": datetime.utcnow(), "user": "Hehehehe!"})

from time import strptime, time, mktime
t1 = strptime("2017/3/25 13:36:02", "%Y/%m/%d %H:%M:%S")
t2 = datetime.utcfromtimestamp(mktime(t1))
tbl.insert({"timer2": t2, "CC": 12345})
tbl.insert({"timer2": 123, "TT": 1})  # TTL-index字段也可以是其他值，这是就不能被自动删除
cli.close()
