Tch, they're not really planets, right? I mean, if they're not orbiting a star, then they can't have "cleared the neighborhood of their orbit". Yet one more reason the IAU's current definition is so idiotic. (Besides the fact that it suggests that Mercury is more like Jupiter than it is like Ceres.)
Yes, they are planets most likely, because they probably formed around a star and then got kicked out dynamically. This is expected generically in models of how solar systems form and evolve (in particular we think it happened multiple times in our own Solar System).
Why adjust for solar time?
We adjust for solar time because UTC is an astronomical timescale, not a "count of seconds since a specific time." If "computer people" want a timescale that ignores leap seconds, they can use an atomic timescale like TAI (or GPS time, which is a constant offset from TAI). But choosing to standardize the internet on UTC and then complaining it is too hard to do the programming right is a little like buying a house next door to a turkey farm and complaining about the smell.
