Interestingly neither does the 15th edition have a discrete article on spacetime, but it is discussed under the title "Time", And the reference I suspect is used for the section on space-time is likely Problems of Space and Time, 1964, J.J.C Smart (ed.).
The article on time itself is signed by someone who goes by the initials J.J.C.S, coincidence, you be the judge....
I found the content of the 13th edition article "space-time", which actually is used as a reference in Wikipedia's [[Spacetime]]. http://www.britannica.com/eb/article-9117889/space-time
I couldn't find any cites, but it's possible they were left out of the online edition, or that I missed them.
