The bug is indeed easy to fix. What's harder is to figure out how things
*should* work as you point out:

o where should it start? should the timeline include past dates by
  default? when the user says so? should it *ever* include past dates?

o where should it stop? The last explicit entry is one possibility,
  user-input is another (but this would require changes to the user
  interface), a time limit specified by the user in some configuration
  variable is a third.

The more one looks at these things, the more one marvels at the choices
that Carsten and Bastien and Nicolas and the Babel developers (and on and
on) have made: getting things so that they work *just* right most of the
time and providing enough flexibility to cover most of the remaining
cases is hard work.
