Well, there is an example: The Sierichstraße in Hamburg is a one-way 
street where the direction of traffic changes daily at 4:00 and 12:00. 
Garmin respects this with City Navigator as I have just tested.

Swiss mountain passes might help as well to understand the mechanism as 
they are blocked in Winter and disallow routing.
