python生成毫秒级时间戳

需求：需要大数据测试考勤时间，生成一些范围内的秒级时间戳

思路：使用faker.random_int方法生成13位时间戳，然后返回一个数组

备注：本身是希望找到faker库中的方法，发现并没有找到

from faker import Faker
import time
from datetime import datetime
fake= Faker(locale='zh_CN')

def change_time(timestr):
    datetime_obj = datetime.strptime(timestr, "%Y-%m-%d %H:%M:%S.%f")
    obj_stamp = int(time.mktime(datetime_obj.timetuple()) * 1000.0 + datetime_obj.microsecond / 1000.0)
    return  obj_stamp

def get_time(time1,time2,num):
    time1=change_time(time1)
    time2 = change_time(time2)
    L=[]
    i =0
    while i<num:
        f = fake.random_int(min=time1, max=time2)
        l1=L.append(f)
        i =i +1
    return (L)
if __name__ == '__main__':
    time1 ="2020-09-24 15:42:15.112"
    time2 = "2020-10-24 15:42:15.112"
    L= get_time(time1,time2,10)
    print(L)
