Putting time onto opening screen

When I turn on my phone, there is a screen with a version of my wallpaper which has a random thing on it telling me how many minutes of peace I’ve had. I’m calling this my opening screen (if I want to go further, I touch it, and go through my security to get to active home screen). So my question is how could I get that opening ‘wake up’ screen to show the time rather than how many minutes peace I’ve had? I’ve not found any menu that seems to allow for it.
