Known Issues: 
None. The website works according to the specifications. 
I prefer the date and time format that I used on my website, even though
it differs from the sample website. 

How I accomplished the random quote: 
I seeded the PHP random number generator with an integer representation
of the current day (e.g. 20240212 for 12 February 2024), and so the
first random number generated from this is always the same, as long as the 
date is the same. 

I chose to update the time and date on the website every 10 seconds instead
of every 60 seconds. It seemed like a good balance of being precise enough
while not sending too many AJAX requests. 

There is a file in the "scripts" subdirectory
called "time.php" which, upon request, hands back the current date and time,
in my preferred format, which is printed verbatim in the HTML.
