Get the status from cli

I what to know if this app is activate or not from zsh, or further, I want to know the remain of activate time. 
Is there some command to do this? 

I want this command returns remaining seconds of activate. If it's not activate, then return 0. If it's activate with no time limit, then return -1. 

This future can combine this app with others, such as bartendar or alfred.
