 # Clock
 
-We have a `Clock` interface which enables you to replace the actual clock implementation in your services for testing
-purposes. We are using this clock to create the `recorded_on` datetime for the events.

-!!! note

-    The `Clock` interface is PSR-20 compatible. For more information see [here](https://github.com/php-fig/fig-standards/blob/master/proposed/clock.md).
+We are using the clock to get the current datetime. This is needed to create the `recorded_on` datetime for the events.
+We have two implementations of the clock, one for the production and one for the tests.
+But you can also create your own implementation that is PSR-20 compatible.
+For more information see [here](https://github.com/php-fig/fig-standards/blob/master/proposed/clock.md).
