After some back and forth, I think the conclusion for now was that
the timestamps in the current v3 format are sufficient until 2106
as long as we treat them as 'unsigned', so we don't need the new
format for y2038, but if we get a new format, that should definitely
use 64-bit timestamps because that is the right thing to do.
