Are you looking to print to the CCS console using something like printf()? If so, you can do that, but just bear in mind that C I/O routines like printf use a fair amount of memory that some MSP430 devices may not have the space for. An alternate option would be to route the standard output to UART interface.

Please take a look at the following pages for additional details:

Please note that difftime returns a double floating-point value, so you need to make sure that you are including <time.h>, that your printf statement uses the %f format, and that you have --printf_support=full on the compiler command line. This is in addition to the requirements outlined by Aarti.
