I'm not sure what you mean by "The OSM API doesn't make the timestamps
public anyway." I just downloaded a random trace (not one of my own) from
the GPS traces tab, and the timestamps were in there.
I can see why Thomas might want to obfuscate his timestamps. Say his
timestamps show that he was driving over the legal speed limit (driving to
his girlfriend's) or under the minimum speed (driving from his
girlfriend's). :-) Unfortunately, time shifting won't change that.
