Time seismograph

A time seismograph, so named by Olive Hashimoto is an object invented by Sander Storm with assistance from Oliver Quimby, Douglas Davenport, and Brandon Frangipani to detect time aberrations.

History
Sander, Oliver, Brandon, and Douglas constructed a device to help pinpoint the epicenter of time quakes in order to prevent temporal aberrations before they happen. While in the Waverider's library, Olive and Sander witnessed the device working and it detected an aberration originating in December 7, 1987 during the United States' and Soviet Union's negotiations surrounding the INF Treaty.

The seismograph later detected another aberration originating in Colorado in 1874, centered around Quentin Turnbull's establishment of his own country in the Old West.
