Question: I am working on a nodejs twitter api and it's working perfectly fine in the local env but when I try to containerize, it fails with a 401 error from twitter.js which is "HTTP 401 Unauthorized client error status response code".

Error

```
> node app.js

Error: Status Code: 401
    at Request.<anonymous> (/usr/src/app/node_modules/twitter/lib/twitter.js:277:28)
    at Request.emit (events.js:315:20)

```

I did my search on this where I found that this could a time mismatch issue in the docker container. My docker container is running 1 and a half hours behind the actual time. I am not sure if this is the only issue.

My docker file

```
FROM node:13.13.0-alpine

# Create app directory
WORKDIR /usr/src/app

COPY package*.json ./

# Bundle app source
COPY . .

ENV KAFKA_HOST=localhost:9092 \
    KAFKA_TOPIC=tweetstream 

CMD ["npm", "start"]

```

How can I set the right time in this docker image?

Answer: 
My problem was that the emulator I was using had `airplane mode` turned on (because I tested related functionality). The problem resolved when I turned it off, thus enabling network to operate as usual.
```
yarn start web

```
