Detecting client-side time of day

I'm having trouble detecting the time of day a client has chosen to view the world in.

I have lights that supposedly turn on and off depending on the time of day it is yet if I were to change my client settings to night nothing would register with the lights. Is there a way to present the state of an object differently for each user depending on the time of day he/she is viewing the world in?

You can't. The simulator has no idea of the client time-of-day override setting.

I want control over how people see my content. If that means a particle-based diffuse glow around my lights at night, 'subjective' or not, I'd expect there to be a way of doing it.

Is there really no way?

No improvisation anyone can think of?
