And agreeing with interchange partners when transactions occurred.

The bank we provide services for has a GPS receiver attached to the DNS
server at each computer centre. These have rooftop antennas with 360
degree horizontal and 180 degree vertical visibility. They've been in use
for at least 6 years. They all peer with each other. At the time they were
considered expensive. They wouldn't be today.

Now if we could just convince Security to configure all the firewalls to
provide NTP service to systems inside the various DMZs we could match up
all the logs.
