The time travel machine knows when it is at all times. It knows this because it knows when it isn't. By subtracting when it is from when it isn't, or when it isn't from when it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to direct the time travel machine from a time when it is to a time when it isn't, and arriving at a time when it wasn't, it now is. Consequently, the time when it is, is now the time that it wasn't, and it follows that the time that it was, is now the time that it isn't.

In the event that the time that it is in is not the time that it wasn't, the system has acquired a variation, the variation being the difference between when the time travel machine is, and when it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the time travel machine must also know when it was.
