- * Test Name: time02
- *
- * Test Description:
- *  Verify that time(2) returns the value of time in seconds since
- *  the Epoch and stores this value in the memory pointed to by the parameter.
- *
- * Expected Result:
- *  time() should return the time (seconds) since the Epoch and this value
- *  should be equal to the value stored in the specified parameter.
- *
- * Algorithm:
- *  Setup:
- *   Setup signal handling.
- *   Create temporary directory.
- *   Pause for SIGUSR1 if option specified.
- *
- *  Test:
- *   Loop if the proper options are given.
- *   Execute system call
- *   Check return code, if system call failed (return=-1)
- *	Log the errno and Issue a FAIL message.
- *   Otherwise,
- *	Verify the Functionality of system call
- *      if successful,
- *		Issue Functionality-Pass message.
- *      Otherwise,
- *		Issue Functionality-Fail message.
- *  Cleanup:
- *   Print errno log and/or timing stats if options given
- *
- * Usage:  <for command-line>
- *  time02 [-c n] [-e] [-f] [-i n] [-I x] [-p x] [-t]
- *	where,  -c n : Run n copies concurrently.
- *		-e   : Turn on errno logging.
- *		-f   : Turn off functionality Testing.
- *		-i n : Execute test n times.
- *		-I x : Execute test for x seconds.
- *		-P x : Pause for x seconds between iterations.
- *		-t   : Turn on syscall timing.
- *
- * History

- * Restrictions:
