I was thinking in terms of grouping, time arithmetic, min/max...

Indeed and same here.
With the solution of George C. Bina in mind, I wanted to give the XSLT 2.0 approach a new try. Well, it ends up somewhere high in the obfuscated code bin, I believe. Here's the tree-walking algorithm from George applied in a single XPath 2.0 expression:

times/time[@time = ../../cells/cell[last()]/@endTime]/following-sibling::* |
times/time[@time = ../../cells/cell[1]/@startTime]/preceding-sibling::* |
times/time[@time = ../../cells/cell[@endTime != following-sibling::*[1]/@startTime]/@endTime]
/(self::* |
[@time = ../../cells/cell[@startTime != preceding-sibling::*[1]/@endTime]
except preceding-sibling::*))

I leave the explanation of this monster as an exercise to the reader ;) I just wanted to find out whether the OP's request was doable on one line (and I am sure it can be done more concise and hopefully without the expensive 'except' operator, I tried '>>' etc, but had some context-node problems).
