Description Nicolas Dietrich 2008-10-01 22:06:49 UTC

Version:           1.4.1 (using KDE 4.1.1)
OS:                Linux
Installed from:    Debian testing/unstable Packages

It'd be a useful addition to allow the animation time step to be set to a sidereal day (23h, 56min, ...). 

Doing that one can observe the standstill of the stars while the solar system objects move.

This could be achieved by adding a separate unit 'sidereal day' between hour and day in the time step control.

Simple patch replacing 12 hours time step by the siderial day.

A trivial fix is replacing another time step (e.g. 12 hours, which is not very interesting) by the siderial day.

This can be done by applying the attached patch to widgets/timespinbox.cpp of the kdeedu 4.1.1 source (haven't checked trunk). 

This isn't particularly pretty but does it for me.

SVN commit 909033 by asimha:

Applying Nico Dietrich's patch (modified) to add a Sidereal Day
time-step to the Time Spin Box.

Nico's patch would replace the 12 hour timestep with a sidereal day
timestep. Instead of doing that, I modified the patch to retain the 12
hour timestep and add a sidereal day timestep as well.

Thanks Nico! This closes wishlist bug #170583.
(Thanks Médéric, for pointing this out)
