Barrett, I generally agree with everything you said, I'm not disputing
anything here...

... except I'm kinda vague on how OBD II works.  When OBD II records a
fault, doesn't it time and date stamp the event?  In this regard, maybe the
car's system does care what day it is.  Except, I can't imagine this
causing the car to stop running, it seems to me it would just interfere
with the ability to record the date of some emissions part failure.  But,
what do I know, I'm no Jim Conforti...

Just wondered.
