python3 获取当前日期的时间戳，以及n天后的日期时间戳

#coding=utf-
import time
import datetime
t=datetime.datetime.now()

#当前日期
t1 =t.strftime('%Y-%m-%d 00:00:00')
#转为秒级时间戳
start_time=time.mktime(time.strptime(t1, '%Y-%m-%d %H:%M:%S'))
#转为毫秒级
print(str(start_time*).split(".")[])

#30天后
t2=(t+datetime.timedelta(days=)).strftime("%Y-%m-%d 00:00:00")
#转为秒级时间戳
end_time=time.mktime(time.strptime(t2, '%Y-%m-%d %H:%M:%S'))
#转为毫秒级
print(str(end_time*).split(".")[])

输出
