**OT** and Sunday is also a slow day

OT Question: "computers in the same office"

Zeev,

Could you please give a short & simple description of the
signals from satellites used in the global-positioning system.

If i make the assumption that any signal can carry data,
and under water communication without the use of a wire,
for example a submarine, is limited by the water absorbing
the signal, what building materials that an office may be
surrounded by would prevent using the global-positioning system.
---
... computers use their internal clocks to timestamp new files,
but changing the clock is a simple trick even for a notice.
... anyone can give the impression they were hard at work
on a Saturday afternoon when they were really at home
in front of the television.

... how the new time-stamp technology works are secret,
Hed says it has a global-positioning system which uses
time signals from at least three satellites to fix
its exact location on the earth's surface.

... each file [encrypted] giving it a unique time and space identity.

Different computers in the same office will give different locations
because of the accuracy of the GPS system [to] identify
the computers being used in on-line transactions, so that
only computers in "authorized" locations can be used.

... cites cases where fraudsters have managed to divert
cargoes of oil while the tankers were at sea,
because their captains were unable to authenticate
the source of purchase orders...
