Here is the background information on your task

We have signed a new account $-$Daikibo Industrials, a global leader in the manufacturing of heavy machinery, founded and headquartered in Tokyo, Japan. They needed assistance with a variety of problems and were impressed to find out Deloitte could help in all verticals.

Daikibo is in the process of integrating IIoT $($Industrial Internet$-$of$-$Things$)$devices to monitor, measure and analyze their manufacturing processes. Half of their infrastructure uses devices streaming telemetry data in one format, and the other half $-$in another. They need your help to combine the two.

Here is your task

Take the following steps to complete the task:

Create an account at repl.it$.$

Fork this project into your workspace.

After navigating to the project $-$find the Fork button on the page and press it$.$

Get acquainted with the $2$data formats by exploring the files $($hint: it's the same message, represented in $2$different formats$)$:

data$-1.$jsondata$-2.$json

Explore the target unified format by looking at the file data$-$result.json. This is the format you should aim to output in your solution.

Complete the solution located in the file main.py$.$

The project is setup in a way to test your solution automatically as you run it$.$

Find the $2$functions in need of implementation and finish them $($look for comment lines starting with "IMPLEMENT:"$).$

Use repl.it to run your project and test your solution $($look for a big Run button, currently located at the top$).$

Don't mind the red color of the console output and the message on failed repl process when you run the project $-$the important thing is to see no failures in the tests.

Successful tests produce output looking similar to this

Please use comments in main.py$,$if you need to leave notes on your solution.

Hint: notice the timestamps of the $2$telemetry formats are different, but the target format is exactly like one of them $($milliseconds$).$You will need to convert the other format $($ISO$)$to it$.$Check the resources for a link to a SO post that can help.

In the next step you will submit your solution.
