21  * Test Name: time02
22  *
23  * Test Description:
24  *  Verify that time(2) returns the value of time in seconds since
25  *  the Epoch and stores this value in the memory pointed to by the parameter.
26  *
27  * Expected Result:
28  *  time() should return the time (seconds) since the Epoch and this value
29  *  should be equal to the value stored in the specified parameter.
30  *
31  * Algorithm:
32  *  Setup:
33  *   Setup signal handling.
34  *   Create temporary directory.
35  *   Pause for SIGUSR1 if option specified.
36  *
37  *  Test:
38  *   Loop if the proper options are given.
39  *   Execute system call
40  *   Check return code, if system call failed (return=-1)
41  *	Log the errno and Issue a FAIL message.
42  *   Otherwise,
43  *	Verify the Functionality of system call
44  *      if successful,
45  *		Issue Functionality-Pass message.
46  *      Otherwise,
47  *		Issue Functionality-Fail message.
48  *  Cleanup:
49  *   Print errno log and/or timing stats if options given
50  *
51  * Usage:  <for command-line>
52  *  time02 [-c n] [-e] [-f] [-i n] [-I x] [-p x] [-t]
53  *	where,  -c n : Run n copies concurrently.
54  *		-e   : Turn on errno logging.
55  *		-f   : Turn off functionality Testing.
56  *		-i n : Execute test n times.
57  *		-I x : Execute test for x seconds.
58  *		-P x : Pause for x seconds between iterations.
59  *		-t   : Turn on syscall timing.
