@@ -617,7 +617,7 @@ The `dateModify` takes a modification and a date and returns the timestamp.
 Subtract an hour and thirty minutes from the current time:
 
 ```
-now | date_modify "-1.5h"
+now | dateModify "-1.5h"
 ```
 
 If the modification format is wrong `dateModify` will return the date unmodified. `mustDateModify` will return an error otherwise.
