I've thought about this problem, but it wasn't clear to me what to do.
It seems to me that if you are allowing yourself to take back moves,
the clocks don't really mean anything anyway, so you might as well set
gnuchess to take a fixed time per move.

However, since the feature of letting you take back moves is there and
people are going to use it, I suppose it does make the most sense to
give gnuchess back the time it used thinking about replies to the
moves you took back.  It would not be hard to do that in xboard.  I'll
put it on my list of things to do for a future version.  (If you want
this to work when you're using gnuchess without xboard, that's another
story, and it's not my decision whether to implement it.)  Should I
give the human player back his time too?
