Using the functions in Web Services - Operations

Using the functions in Web Services - Operations

In "Monitors \ Web Services \ Add Operation"

I'm using the function: ${time(yyyy-MM-dd)} and I can return the current date.

I need that returns the current date + 7 Days.

1 -) How do I do this calculation using the function?
2 -) Is it possible to create new function? How?
