This replaces use of the system time command with __DATE__ and __TIME__ I think the following two errors are caused by fedex_plus being rebuilt for each test: Linking CXX executable ../../bin/fedex_plus CMakeFiles/fedex_plus.dir/__/express/fedex.c.o: file not recognized: File truncated and [ 87%] Running fedex_plus for AP214E3_2010... /bin/sh: /opt/step/test-scl/build_ctest/bin/fedex_plus: Text file busy fedex_plus is being rebuilt because the version string changes, since it contains the date and time.
