Having a hard time understanding the getTime() function

What the function's if Statement actually do?

function getTime() {
  function pad(number) {
    if (number < 10) {
      return "0" + number;
    } else {
      return number;
    }
  }

The "if" is just checking to see if the number only uses one digit. If so, the following code converts it into a 2-character string starting with a "0" and returns that instead.

The idea is to make sure the number always uses 2 characters regardless of its value.
