# What time is it? Old Solution

## Description

Help us to translate the given time into a sentence that states that time it self

## Hint

- time : String time that must be translated into a sentence
- if time = 12:00 am return must be "It's midnight"
- if time = 12:00 pm return must be "It's noon"
- else return must be what time is it and it's afternoon or morning

## Examples

> - time = 2:15 pm
> - return = It's two past fifteen in the afternoon

> - time = 8:57
> - return = It's eight past fifty seven in the morning
