<h2>The standard</h2>
<html>
 <head></head>
 <body>
  <p>Different date formats may cause a lot of confusion, so in 1988 ISO officially introduced the standard numeric date format: YYYY-MM-DD. Let's create a function that formats dates in this way!</p> 
  <p>Below you can see a template for the function <code class="java">convert_to_standard</code>. It takes a <code class="java">datetime</code> object and returns the string in the standard format. You can discard hours and minutes, they are not of interest right now. Your task is to finish that function. Pay attention to the delimiters!</p> 
  <p>Note also that you do NOT need to call this function or process the input. The examples are given for clarity!</p>

<b>Caution</b><br><br>
You may see errors in your code or execution results due to missing context. Don’t worry about it, just write the solution and press Check.
