 Have a look at the previous post for details on the *source* values. For reference, the user creation time is provided by the `member_since` column, and one of the values is `April 4, 2014`. The following snippet shows how the various user date related properties are set:
 
-```
-<code class="language-yaml">created:
+```yaml
+created:
   plugin: format_date
   source: member_since
   from_format: 'F j, Y'
   to_format: 'U'
 changed: '@created'
 access: '@created'
-login: '@created'</code>
+login: '@created'
 ```
 
 The `created`, *entity property* stores a [UNIX timestamp](https://en.wikipedia.org/wiki/Unix_time) of when the user was added to Drupal. The value itself is an integer number representing the number of seconds since the [epoch](https://en.wikipedia.org/wiki/Epoch_\(computing\)). For example, `280299600` represents `Sun, 19 Nov 1978 05:00:00 GMT`. Kudos to the readers who knew this is [Drupal's default `expire` HTTP header](https://git.drupalcode.org/project/drupal/blob/8.8.x/core/lib/Drupal/Core/EventSubscriber/FinishResponseSubscriber.php#L291). Bonus points if you knew it was chosen in honor of [someone's birthdate](https://dri.es/about). ;-)

 The rest of the migration is almost identical to the [CSV example](https://understanddrupal.com/articles/migrating-csv-files-drupal). Small changes were made to prevent machine name conflicts with other examples in the demo repository. For reference, the following snippet shows the *process* and *destination* sections for the LibreOffice Calc *paragraph* migration.
