Hi Ruan,
You also need to remove all entries releated to time02, for example:
runtest/syscalls:time02 time02
testcases/kernel/syscalls/time/.gitignore:/time02

It is better to replace the number with '-' so that it follows the
markdown list.

I think we don't need to define two different functions.
How about defining different arguments and then pass them to time()? for
example:
struct time_t *args[2]= {NULL, &tloc};
static void verify_time_store(unsigned int i)
{
TEST(time(args[i]));
......
}
