I think that the "proof" of the timing system would be to record some time
marks right along
side your seismometer. This could be set up with a summing amplifier so
that the time
mark amplitude could be adjusted to a low but visible level. Of course the
time marks must be from
a very accurate source, such as a GPS receiver. The second marks could be
used, as long
as you are confident that the system clock is not off by more than 0.5 seconds.
