Astronomical events can take hours, days or even years to occur. To simulate astronomical
events, you can speed up time using the Control time panel.
If you set time running using the Control time panel, then your position will move to
track the object and your view will be directed according to the location mode that
you have chosen.
After running time you can return to the time from which you started by clicking the button
in
the top right corner of the Control Time panel.
Click the forward or back
arrows in the Control Time panel to run time forwards or backwards
in current time steps (time tracking). You can also start time running by selecting Run Timer
from the Controls menu. If you have the Time panel open while running time you can see that
the current time is being updated with each time step.
Click the Stop button in the
Control time panel to stop time running. Use the buttons either
side of the stop button to step forward or back one time step at a time.
The actual speed at which RedShift can move the objects on the screen depends on the speed of
your processor and the display filter settings. Remember that RedShift accurately calculates
the position of a planet or moon for each new time step; it also calculates where the Sun
currently is in relation to each planet and moon in order to show the correct phase (shadow)
on the surface of the planet or moon.
Edit the current step value in the Step field (click the
current value to select it then enter a new value). This allows you to control the time step
RedShift uses each time it updates the screen (for example you might choose time steps of one
day to watch the Moon orbit the Earth).
Press the first letter of a unit's name in a units fields to change units (for
example press the letter "d" to change the step units to days.
Use the Time Steps pop-up menu to set the units. Select units
of minutes, hours, days or years.
