Not everyone has a RTC on their TI... they think.
If you have a TIPI, the RPi can give you the time in a huge string.
But what if you took a segment of that string and fed the useful portion to the TI's consoles internal clock?
Now just because it can be done, does that mean anyone has a use for it?
I can think of a few ideas, but I'll leave it you to think about them... or not.
