Also, we are only talking about a delay long enough to satisfy the
longest circuit so you could not push your timestamp very far back and
would have to get the fake one done pretty quickly in order for it to be
worthwhile.  The real question is could you fake a cryptographic
timestamp fast enough to actually gain time on the system.  Possibly but
it would be a very tall order.

What prevents someone to fake an earlier timestamp?  Money can bend
light, sure can a few msec.

It seems to me that all the markets have been doing this the wrong way.
Would it now be more fair to use some kind of signed timestamp and
process all transactions in the order that they originated?  Perhaps
each trade could have a signed GPS tag with the absolute time on it. It
would keep everyone's trades in order no matter how latent their
connection to the market was.  All you would have to do is introduce a
couple of seconds delay to account for the longest circuit and then take
them in order.  They could certainly use less expensive connections and
ensure that international traders get a fair shake.
