I think if you have the hours, minutes and seconds defined outside of this function (and the new date as well), then after the server started to run, it will add the exact same time to all posted messages. To capture the actual creation time, the new date have to be created within the function, so it always reflects the time when the function is called.

@GergelyKI Thank you very much, I've fixed it. I'm not sure why bat it shows time 1 hour less than UK TIME.
server.js
Outdated

This way of defining ids might not be the best because the length is not always growing because you can deleted messages as well, and you can end up having messages with the same ids.
e.g. you have to following array: [{id: 0}, {id: 1}]. Then you delete the first one you're left with the array: [{id: 1}].
Now you want to add another one. The length is 1 , then the next id is also 1, and your array will be [{id: 1}, {id: 1}].
Then the ids become ambiguous. Now if you want to delete again one with id: 1 or find one with id: 1, it will return the first one, but maybe you wanted the second one.
(You can use some sort of id generator library like uuid, that will ensure you're ids are always different).
I think the takeaway doesn't have to be about the ids themselves, just that it's always worth keeping in mind the length of the array can change if you come across any indexing problem.)

@GergelyKI thank you very much for your comment, Yes I'll definitely to think about how to fix it) true, not the best way

is this error going to be displayed as the response when I do a POST to /messages without a body.from or body.text?

Good use of functions for each of the endpoints.
