Actually it is incredibly accurate only if you use PPS output otherwise
idea of having atomic clock in your pocket goes out of the window.

GPS essentially *is* accurate timing... GPS satellites are flying atomic clocks.
Trimble has a good GPS tutorial -
After recently having a 5.2 earthquake here in the Midwest, I realized the
potential in the Openmoko for detecting/pinpointing earthquakes. What this
is mostly dependant on is the accuracy of the accelerometers in the
Freerunner. From what I've read, Macbooks' accelerometers and detect and
Sounds like an awesome idea! :D

The detection/pinpointing part requires both accurate detection of shaking
and timing - obviously the
Yes, AFAIK GPS requires accurate time to function.

When I used a bluetooth GPS with my laptop, I notices the gpsd output had a
different time than my system clock showed, so I assume GPS provides its own
clock.
Yes. It does.

Almost all Digital Seismometers have a GPS interface to get the
accurate timing they require.

Yes. It does.
To be a bit more specific:
The GPS gets positional data and time from one or more
satellites. This
