Try JPL's Horizons at
http://ssd.jpl.nasa.gov/horizons.cgi#top.
Here you can input the planet required by hitting [change], and it will give you the light times. Ie. Saturn is 699, Jupiter 599, and it will give you want you want by default. (Explanation is listed below.)
Using the defaults will give you the light-times - hence distance by the hour for the current day. (You can change the span times with ease)
Make sure the Observer Location is "Geocentric" (500) - not Heliocentric as you will be standing on the Sun. [ actually within the Sun for the pedantic]
You can also use the Table Settings for the parameters you want.
