This is a my first mail to LTP mailing list.
I'm testing Linux Kernel 4.2.0 by LTP. I saw a following Error.
-----
settimeofday01 1 TFAIL : settimeofday01.c:98: Error Setting Time,
errno=22
settimeofday01 2 TFAIL : settimeofday01.c:120: Test condition 1 failed
settimeofday01 3 TPASS : Test condition 2 successful

In commit of Linux Kernel:
e1d7ba8735551ed79c7a0463a042353574b96da3 "time: Always make sure
wall_to_monotonic isn't positive"
add a new check to do_settimeofday64().
This commit said:
"As a result one can't set the CLOCK_REALTIME time prior to (1970 +
system uptime)."
In settimeofday01 test case, parameter of first settimeofday() is
100s100μs. A lot of cases, TEST_RETURN is -1.
I'd better to modify settimeofday01 test case.
To meet that requirement, I made following changes.(I have less
confidence that it is correct...)

Thanks.
