13位时间戳转为日期时间、获取当前时间的13位时间戳

import time

# 输入毫秒级的时间，转出正常格式的时间
# def timeStamp(timeNum):
timeStamp = float(1603346322020/1000)
timeArray = time.localtime(timeStamp)
otherStyleTime = time.strftime("%Y-%m-%d %H:%M:%S", timeArray)
print(otherStyleTime)
# timeStamp('1603346322020')

 获取当前时间的13位时间戳

    datetime_now = datetime.now()
    # 10位，时间点相当于从UNIX TIME的纪元时间开始的当年时间编号
    date_stamp = str(int(time.mktime(datetime_now.timetuple())))
    # 3位，微秒
    data_microsecond = str("%06d" % datetime_now.microsecond)[0:3]
    date_stamp = date_stamp + data_microsecond
    stamp = int(date_stamp)
