Usecase-5 itself is a project thus you might need to install dependencies if you haven't installed. If you already ran yarn install on root then the install for this project should also auto trigger.
💻 How to check: Pointing yourself at root of the project run yarn uc5 or simply run yarn dev at root of Usecase5 and you will see the code execution.
We might come across situations where we need to show time based on user's local instead for having a predefined local as shown in Usecase1.
Lets see a concrete example: Lets imagine where we have senTime and receivedTime to be stored on backend which will be converted to UTC+0 by backend and stored in database but we need to show the sent time and received time to two different users at different timezone and that we are completely unaware about the user's local and timezone.
In a nutshell we need following things to happen:
- Show sent time to User1 as per their local
- Send the current time data with timezone information to backend
- Receive the received time from backend for User2 (Which might be slightly different because of processing time)
- Show the received time to User2 as per their local
A short illustration of scenario with example where User1 is from Nepal and User2 is from Japan.
Send and show
User1:[Nepal Time] -------------|
V
Backend:[UTC 0] Retrieve, Send and store
^
User2:[Japan Time] -------------|
Retrieve and Show
As you can see the despite twe could simply send UTC but display the sent time as per the users location.
