+ * Test: y2ktmo
+ *
+ * Description:
+ *   This test tests the interval time facilities in NSPR for Y2K
+ *   compliance.  All the functions that take a timeout argument
+ *   are tested: PR_Sleep, socket I/O (PR_Accept is taken as a
+ *   representative), PR_Poll, PR_WaitCondVar, PR_Wait, and
+ *   PR_CWait.  A thread of each thread scope (local, global, and
+ *   global bound) is created to call each of these functions.
+ *   The test should be started at the specified number of seconds
+ *   (called the lead time) before a Y2K rollover test date.  The
+ *   timeout values for these threads will span over the rollover
+ *   date by at least the specified number of seconds.  For
+ *   example, if the lead time is 5 seconds, the test should
+ *   be started at time (D - 5), where D is a rollover date, and
+ *   the threads will time out at or after time (D + 5).  The
+ *   timeout values for the threads are spaced one second apart.
+ *
+ *   When a thread times out, it calls PR_IntervalNow() to verify
+ *   that it did wait for the specified time.  In addition, it
+ *   calls a platform-native function to verify the actual elapsed
+ *   time again, to rule out the possibility that PR_IntervalNow()
+ *   is broken.  We allow the actual elapsed time to deviate from
+ *   the specified timeout by a certain tolerance (in milliseconds).
