Ugh. Yes. That was always somewhat of a problem in the protocol IMHO. Nobody
needs more granularity than seconds because the main database doesn't have it.
Similar for the latitude/longitude granularity. Nobody uses that. And it just
makes all the code reading PBF files a bit more complex and a bit slower.
