Display the date and time
Created on Dec. 16, 2016 by Julien Palard
Write a program printing the current date (year month day hour minute and seconds) in a human readable format.
It should look like this:
Today is 2015-09-17 and it is 09:34:35.
Beware the width is constant: 9h should displayed as 09:00:00, not 9:00:00, same for the month, day, and so on.
