I'm wanting to convert barycentric julian date to the equivalent UT time. Here is a description of the barycentric julian date given to us:

Barycentric Julian Date (TT) – Observation epoch, given in terrestrial time, that has been corrected for light propagation time to the solar system barycentre.

3. The attempt at a solution

Now I know how to convert Julian date to UT and I know that [tex] Terrestrial Time = UT + \delta T[/tex], where the value dT can be obtained from the web. But I really wouldn't say that I understand or have found a definition of TT that makes me understand exactly what it is. Is the correction for light propagation time to the solar system barycentre just terrestrial time?

Thanks
