I do not think there is much more to do, the timestamp is just a 64 bit
integer and you say an int takes 570ms/10920 calls and a timestamp takes
7130ms/8190 calls, this is about twice as much to get twice as much data.

Yep, but as I said, the others are much faster. E.g. getString takes
140ms for 5460 calls, and getInt 570ms for 10920 calls, so its
probably not so much the profiler.
Also, I was merely asking whether there is something that could be
done to bring getTimestamp at least in the same region.
