On inspection, looks like we don't compensate the offset parameter when the
nanos part is being decoded.

public int decodeInt(byte[] b, int o, SortOrder sortOrder) {
...
if (sortOrder == SortOrder.DESC) {
b = SortOrder.invert(b, o, new byte[Bytes.SIZEOF_INT], 0,
Bytes.SIZEOF_INT);
}
int v = Bytes.toInt(b, o);
