Hello! Please have a look on http://www.osm.org/way/1161156608, http://www.osm.org/node/10799922214. What is the mean of the key "former name"? Did you mean old_name?

The key from, to isn't for time interval (it is the start and end point of  a route).
from = 1928
to = March 26, 1946
The time notation is yyyy-mm-dd (1946-03-26).
