How it´s possible to sign code valid just for 3 months?

Hi Team

I found an application signed in a weird way or at least I don´t have an idea of the reasons… the application has a validity that is lower than 1 year, specifically 3 months. As far as I know a trial for code signing is not allowed by Comodo.

So, could you tell me in which circumstances it´s possible for COMODO to issue certificates with a validity like this??
