I don't know, but can Nintendo check if you are subscribed while you are offline?
I assume it would be similar to the PS+ games on Vita, it'll find out when your subscription expires when you connect to the internet, and keep track based on the internal clock. Though if it loses all power keeping the internal clock alive (that is, you literally remove the battery) it would likely revoke access until the date is set again via the internet. Again, going by what happens on Vita.
