That would be nice it is were a standard and everybody was doing it, because
otherwise, for a day, your own network might be happy, but if you have any app
that needs to communicate with the outside world, you are in a lot of hurt.

FOX news just did a piece on LightSquared and GPS and the general. They
called the general gutsy and are asking who put the pressure on?
They used the analogy of trying to talk on a cell phone next to a rock
concert, BTW.
This story is rapidly growing legs.

You can forget Wall St. firms and Banks for starters.
They need sub-microsecond accurate timing as some instruments (Forex)
are moving to 10 microsecond latency from order entry to order ack.
Although some software (FIXX) needs a lot of work to get there, they
are moving in that direction.

By the way the USG is so concerned with the LS pollution, that they are
conducting a WORLDWIDE survey of existing equipment/systems that would be
impacted by L/S, on the assumption that the modus perversion will spread

10 microsecond latency doesn't say anything about how accurate the time
You are right.
To be more precise, I should have said that the time sync should be at
least 1 order of magnitude less. In the case of 10us turnaround time,
it is assumed that the timesync is 1us. This is the reason that
everyone uses multiple stratum 1 NTP servers using GPS in their

I just read they were building a new transatlantic cable that will shave 10uS
from the normal 60 or so uS and that for large traders, 1uS represents 100
million $ per year saving/increased revenue.

Should not be ms instead of us for a transatlantic cable? 60us at light
speed is only 18km ;)

With the recent wild fluctuations in the Commodities markets it is
incredibly important that time delay between any 2 parties (in a
financial transaction) be reduced to a minimum.
Only a few years ago, gold, silver and oil would vary by a few dollars
(at most), intraday and even intraweek.
Bring back the transaction tax and I suspect these timing issues will go away.
I recall reading the London exchange was experimenting with linux and mysql,
supposedly faster than what they were using.

All this fuss over microseconds being worth billions and it still takes a
