由于服务器时间差异导致python中的Tweepy 401错误

I am trying to retrieve Twitter data using Tweepy, using that below code, but it returns 401 error, and I regenerated the access and secret tokens but didnt make a difference

我试图使用Tweepy检索Twitter数据，使用下面的代码，但它返回401错误，我重新生成访问和秘密令牌但没有什么区别

#Import the necessary methods from tweepy library
from tweepy.streaming import StreamListener
from tweepy import OAuthHandler
from tweepy import Stream

#Variables that contains the user credentials to access Twitter API 
access_token = "ENTER YOUR ACCESS TOKEN"
access_token_secret = "ENTER YOUR ACCESS TOKEN SECRET"
consumer_key = "ENTER YOUR API KEY"
consumer_secret = "ENTER YOUR API SECRET"


#This is a basic listener that just prints received tweets to stdout.
class StdOutListener(StreamListener):

    def on_data(self, data):
        print data
        return True

    def on_error(self, status):
        print status


if __name__ == '__main__':

    #This handles Twitter authetification and the connection to Twitter Streaming API
    l = StdOutListener()
    auth = OAuthHandler(consumer_key, consumer_secret)
    auth.set_access_token(access_token, access_token_secret)
    stream = Stream(auth, l)

    #This line filter Twitter Streams to capture data by the keywords: 'python', 'javascript', 'ruby'
    stream.filter(track=['python', 'javascript', 'ruby'])

The code is available here

代码可在此处获得

I know for a fact that all the other things in the code are right and there are no syntax or authentication error. I read in an answer for the question that 401 error is also because of server-client time difference.

我知道代码中的所有其他内容都是正确的，并且没有语法或身份验证错误。我在一个问题的答案中读到401错误也是因为服务器 - 客户端时间差异。

My question is: To what do I set my system time to overcome this error? Or in other words how do I know the server time so as to change my system time?

我的问题是：我应该如何设置系统时间来克服此错误？或者换句话说，如何知道服务器时间以便更改系统时间？

When you send an HTTP request to the Twitter API server, it will send a response back. You should capture the response headers, which will include their server time, like this:

当您向Twitter API服务器发送HTTP请求时，它将发回响应。您应捕获响应标头，其中包括服务器时间，如下所示：

It's using GMT, so if your server is set to a different time zone, adjust for the time difference.

它使用GMT，因此如果您的服务器设置为不同的时区，请调整时差。

I used Fiddler and got this response from the OAuth request token (https://api.twitter.com/oauth/request_token) endpoint - so, you don't have to be authorized before being able to do this.

我使用Fiddler并从OAuth请求令牌（https://api.twitter.com/oauth/request_token）端点获得此响应 - 因此，您无需获得授权，然后才能执行此操作。
