The distance information is given in light years to two significant figures. The source data gives higher precision, but I'm not sure of its accuracy. The star colours as drawn on the map are very crudely estimated from the B-V colour index. Don't use them for anything important.
You can enter years between 0 and 9999. For dates far in the past or the future, the stars' proper motion and the precession of the equinoxes are taken into account. The search feature for stars is less effective far into the future, because although the image generator takes account of precession, the script doesn't.
A star's proper motion is its apparent drift relative to other stars over the centuries.
Precession is the gradual drifting of the equinoxes over thousands of years. In 13,000 years time the pole star will be Vega; that's precession.
Star information is from the HYG database compiled by David Nash. Everything listed under "Database Quality Issues" there applies to information on this page.
Planet information, co-ordinate transforms, time calculations and lots of other things were made many times easier by the libnova library.
