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