-#### Conversion
-
-The `Time` object can be converted to a string with the `toString` method or just casting the object to a 
-string `(string)$time`. This will output: `14:30:15`. You are also able to show the time without seconds when using the
-`format` method.

 #### Difference
 
 The time object can also be used to calculate the difference between time objects:

+#### Presentation
+
+The `Time` object can be presented as a string with the `toString` method or just casting the object to a
+string `(string)$time`. This will output: `14:30:15`.

+There are also two other presentations available, the `toNumericalTime` and `toReadableTime`:

 #### Comparison
 
 The `TimeRange` object makes it easy to compare to a single `Time` or another `TimeRange`.
