To be fair, this is more an exercise in taking "future-proofing" to a logical extreme than something practical (or even possible).
With that context I (arbitrarily) chose plank time to be the smallest possibly-ever usable (maybe not practical) time scale for timekeeping.
That's a good point about location. If we're going for extremes, we should put it in one of the especially large spaces between galaxy clusters: supervoids[0]! If there were a clock made at plank time frequency, I wonder how much of an effect structures would have on it at interstellar, intergalactic, and void space distances. At this accuracy (and these distances) I imagine the clock's own gravity would be a major source of time dilation.
Perhaps the best setup would be an extremely small (think the size of a virus) clock with a small support station that provides energy to it and reads ticks back, kept a few hundred thousand light-years away to avoid gravitational influence.
Another thing. 10^100 years is a long time. So long that if the time from the big bang to the heat death of the universe were one second long, the universe isn't even 1 plank time old yet. 10^100 years is so long it starts making sense to talk about the half-lives of elements that are considered perfectly stable. To make any clock that is designed to operate continuously for that long would be a crazy undertaking even for an interstellar civilization.
