Add interval to current date and dispay result in views

Question

I have a field in one of my content-types that contains a interval (using the interval module). I have configure the field so that the user can select how many years a curtain certificate should be valid.

How can I add this interval to the current year and count how many results I got using views?

Answer 1

Have you tried the Views Calc module?

The other option would be to use the Computer Field module but that could be risky as you enter PHP code into the field.
