I had a neighbor with Alzheimers who was often confused about whether it was morning or evening (she only had analog, 12-hour clocks). She seemed to have two days per day, and I'd often hear her 6am alarm go off at 6pm.
I made a simple web app for her that showed the time along with the bold text MORNING, AFTERNOON, EVENING etc. I set this up on her tablet by the wall, but every time I visited it had been switched off (all the way), and she had no memory of it being set up. (Presumably her bedtime routine involved "turning off the computer"...)
So I just bought her an analog Alzheimer's clock (a 24 hour clock with some colors and pictures to indicate the time of day -- quite similar to OP's design actually). She took readily to that one.
