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 detectors around the earth. With good clocks, you can
work out the direction it came from. The timing has to be good within a
fraction of a wavelength. Maybe less if you can live with reduced pointing
accuracy. (VLBI astronomers use hydrogen masers.)
In 1987, 3 neutrino observatories observed a supernova.

But their timing is far from good enough to work out the direction. (Their
fundamental detector technology is slow.)
It might be possible to get a more sensitive system if you have a detector
that is low cost so you can sprinkle many of them around around the Earth.
With good clocks, phased array type math will give you antenna gain if you
have enough compute power to search the whole sky. (or know where you want
to look)
