Yes, one can see that implemented here:

 https://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/CTest/cmCTestTestHandler.cxx;hb=v3.4.1#l1112
 https://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/cmCTest.cxx#l2108

Here is a commit that set the order of precedence:

 Local test timeouts will now always take precedence over the global --timeout option.

>From the history of that code it looks like --timeout was added with
no consideration of its relationship to CTEST_TEST_TIMEOUT.  Some
other CTest options in the same scope as CTEST_TEST_TIMEOUT can be
overridden by the command line, so I agree that --timeout should
override it too.
