Feature Request: Select Start Date at the Weppage's: Ephemeris

Hi,

I have a Feature-Request please, if possible: To select the start date at the vsx Weppage of the Ephemeris Javascript.

Someties if I go over old data, I want to check the TOM's, and it would be handy, if one can select any old date, to calculate further old TOM's, for comparison reasons.

Now it only calculates TOM's only from the actual date.

?
