The "Visible" Solar System
1) Use checkboxes (Seconds, Minutes, etc) to choose time interval. "Days" works best for animation.
Use slidebar at right to control simulation speed. There are 7 speeds, 3 forward (right), 3 reverse (left) and one neutral
(center), although depending on your computer speed, there may be no difference between the two faster speeds. The
bar is initially set at the slowest forward speed. Use "Reset Time" to return to present.
2) There is still a problem with the local time - it does not take into account the shift to/from Daylight Savings Time,
and so may be off by an hour. Universal Time will always be correct.
