testcases/open_posix_testsuite/conformance/interfaces/clock_settime/8-1.c:
 * Steps:
 * - get time T0
 * - in child:  set clock_nanosleep() to sleep for SLEEPSEC seconds
 * - in parent:  sleep SMALLTIME (< SLEEPSEC)
 * - in parent:  set time back to T0
 * - in child:  ensure time when clock_nanosleep() expires is within
 *   ACCEPTABLEDELTA of T0+(SLEEPSEC-SMALLTIME)
...
#define SLEEPSEC 5
#define SMALLTIME 2
#define ACCEPTABLEDELTA 1
