EOBT is Estimated Off Blocks TIme: The flight plan time for the flight to be ready for departure. ATC usually allow a tolerance of +/- 15 minutes.

TOBT, Target Off Blocks TIme, is a more accurate measure, usually within +/- 5 minutes, which tells the local CDM system and NMOC Brussels when the airline believes a flight will be ready.

From this, a TTOT is calculated (Target Take Off TIme), which may be adjusted to allow for departure separations, CTOT etc, and then working backwards will provide a TSAT (Target Start Approval TIme) which will provide both ATC and the airline the most suitable start up time given all the factors that the local CDM system takes into account.

Maybe this helps a little....

Airport CDM @ FRA | Overview (http://cdm.frankfurt-airport.com/content/fraport-cdm/en/acdm_-_overview.html)

It's FRA's way of trying to explain it...
There are several folders to click on with various explanations of TSAT, EOBT, TOBT etc.

Greets,
