Falcon:

State lines are simply survey lines, whether curved or straight, and have no width dimension. The coordinates of these lines do not change as the day progresses.

When geographic datums change, say NAD (North American Datum) 27 to NAD 83, there are mathematical adjustments necessary to adjust for the new datum, but the actual coordinate positions (and resultant lines) remain the same.
