IIRC almost all the signs in the swiss alps are time, not distance. Which makes sense given how steep many of them are -- even if it's not your pace, it's a quick summary of distance + elevation. Perhaps this is less needed in Czech terrain. They are also coloured by difficulty, not length -- yellow will be a big wide road, red a mountain path, blue may expect you to have brought crampons.
