Something to do with the current time, or sun cycle, but let's take baby steps here.
Perhaps it could go something like this:
@123(Current Swatch Internet Time, iicc))/(Literal divider))21(Current military time))
This would demonstrate the time of day, and the worldwide time.
I am not saying I would endorse this, as I'm sure there's flaws I have yet to see. I don't even endorse Swatch time, but I acknowledge it's pros despite finding them useless. Merely playing the advocate of the Devil.
