+ * 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).
