The times structure can be initialized inline as:

static struct utimbuf times = {
	.modtime = NEW_MOD_TIME,
	.actime = NEW_ACC_TIME,
};

The PASS/FAIL message is already printed by the TST_EXP_PASS() macro,
all that you need to to do here is return.

We do have macros for these kind of checks as well, please use them as:

	TST_EXP_EQ_LI(stat_buf.st_atime, NEW_ACC_TIME);
