(T.L. = E.L. + 1.002738*ΔT/240, where ΔT(in seconds) = TDT - UT) Note: Longitude is measured positive to the East. Since ΔT is not known in advance, the value used in the predictions is an extrapolation based on pre-2004 measurements. Nevertheless, the actual value is expected to fall within ±0.3 seconds of the estimated ΔT used here.
