Timeline Discordance Analyzer

The Timeline Discordance Analzyer (TDA) was invented by Aloysius Atherton in 1878. It is used to detect and analyze objects or individuals that are suspected of time traveling or of being in the 'wrong' time.

In the presence of an object which is out of phase with its timeline, the crystal of activated triphasic selenium will begin to glow: green if the object has moved past-to-present or red if future-to-present. The intensity of the glow indicates how far out of time the object or preson has traveled.

It is self-calibrating for use in any time period.

The TDA may be used in conjunction with a temporal quanitification interfact (TQI) to pinpoint the precise time of origin. Later models of the TDA incorporate this feature.

An essential tool for any timeline action or investigation, some type of TDA has been standard issue for Time Defenders since the formation of the Council.
