Of course, a collection of distributed, very accurate clocks does
already exist:

And there was a recent paper using this with a similar approach as you
are suggesting, not for gravitational waves, but in the hunt for dark
matter:
If I understood it well, we should occasionally encounter gravitational
waves going through, well, the whole galaxy. As time and space are
intertwined, those ripples may be measured somehow I guess.
Isn't this that we as time nuts community can help the scientific
world with? E.g. create some
Conclusion: not feasible.
Actually, timing isn't the critical part. Yet. First you have to detect
something.
If you have only one working detector, timing isn't very important. If your
detector doesn't tell you the direction, you can build a phased array antenna
by putting several

Using relativistic effects on time to sense gravitational changes
is like using dynamite to clean barnacles off of a boat... you can
do it, but surely there is a better tool?
A large part of the dithering about of precision analytical scales
is due to gravity

Hi
Indeed the time nuts world does intersect very directly with this problem. One
of the major drivers for some of the JPL work done back in the 1980’s was to
come up with stable enough sources to mount on a deep space probe. The intent
was to detect gravity waves. There is always a gotcha, in

To do this you'd need a clockso accurate that it will run at the different
speed when you move it from the bottom to the top

Our clocks aren't good enough.
It's a very hard problem. Here is the scale:
Well, funny you should mention laser inteferometry. My old company
designed the shock mounts for the LIGO gravity wave detector.

So far they haven't seen any signal in the noise.

Yes. There are experiments set up in the US, in Italy and in Japan, to detect
gravitational waves, funded by various universities.
So
My Mickey Mouse watch was... it detected a gravity anomaly when the strap
broke and it hit the garage floor. This apparently caused a complete cessation
of temporal flow around the unit, ;-)

When LIGO was announced I read up on it as much as I could.
The problems seemed enormous.
Bob Darlington mentioned shock mounts. That in itself seemed
like a show stopper.
Then I think there was some kind of accident. Anyway
these guys did finish the LIGO. But unfortunately
no space differential
Folkert,
If we had a 'Time Quake' - would we even know?

A VERY accuracy clock is actually a good sensor for gravity. This is
because the clock's speed changes with strength of the gravity because of
Einstein's General Theory. So if you have two very good clocks that are
separated if one starts to run faster then we can assume time itself is
running
