Ok, this is what I do:

I set Redshift's time to 03/20/2004 06h:48m which is the time for the

vernal
equinox this year
Set the sun's image to "icon". Look at the sun, it is over the vernal
equinox.
Now enter 2000 and select Tropical years in time step. Press time step
forward once. The time now is 03/19/4004 15h:55m.
Look at the sun: It has displaced from the vernal equinox and you need to
move the time forward about 10 hours in order to put them together again.
Anyone has an explanation?


My guess is that it's caused by the position of your observing point on
the surface of the Earth, and that things would behave as you expect if
the observing point were the centre of the Earth. Or move your observer
to the point on the equator where it's local noon at the instant of
equinox.
