Yes. The TEP is out of sync with the code. TimerMilliC is now a  
generic, and HilTimerMilliC is the HIL that a platform MUST provide.  
Basically, make the TEP agree with the code.

Currently, HilTimerMilliC is in the chips/msp430 directory, when it  
should be in platform directories.

The question here is whether we want to require LocalTime, and what  
its semantics are. For platforms that do not have a low-power  
external oscillator, then if we make LocalTime a MUST and say that it  
runs continuously, this could preclude low-power operation. The  
question is whether we want to preclude all of those devices from  
being TEP 102 compliant.
