You need to create a custom function (e.g. getTime_custom_fake) to produce the output optionally by use of a helper variable (e.g. getTime_custom_now) to retrieve that output from. Then some creativity to tie it all together. The most important part (IMHO) is to keep your test case readable and maintainable.

In case your project uses a C99 compliant C compiler you can even combine all this in a single unit test function so you can easily oversee all details of the test. See the example below.
