 We will start by defining the block structure. Only the most essential properties are included at the block at this point.
 
 * `data`: Any data that is included in the block.
-* `timestamp`: A timestamp using ISO format.
+* `timestamp`: A UTC timestamp using numeric format.
 * `nonce` : A number of attempts to generate the correct hash.
 * `hash`: A sha256 hash taken from the content of the block.
 * `previousHash`: A reference to the hash of the previous block.
