Comment 6 for bug 1380242

Hi Victor,

Yes, I have verified the result. The same instant as displayed in the
Date/Time window produces the same sky no matter which Delta T model is
used (but I didn't try them all).

And, yes, I definitely believe we should propose that Stellarium should
use UT as its user timescale.

Cheers,

Frank
