Devise: Log user out after the confirmation period ends

I have a setup for logging the user out of the application once the confirmation period ends. Also, I need the user to be only logged out at night at 2 AM.

For this, I overrode the following -

def confirmation_period_valid?
  confirmation_time = confirmation_sent_at.in_time_zone(time_zone).end_of_day + 2.hours
  unconfirmed_access_time = self.class.allow_unconfirmed_access_for.ago.in_time_zone(time_zone)
  confirmation_sent_at && confirmation_time >= unconfirmed_access_time
end

But when I check after the expiration period, I am still able to use the application. The user is not logged out.

Checking the rails console shows that the confirmation period is not valid for the user so that works.
