Before we get into the details of how this timestamp is implemented in the PBF
format, maybe somebody can define what this timestamp is actually timestamping?
Is it the time the file was created? The last changed object in the file? The
time the database extract was created? Something else?

I guess the timestamp is somehow supposed to say which state of the OSM
database this file represents. How is it supposed to work in history files?
Do we need two timestamps to define a range for history files?
