+// Description:   Tests the Kernel Real Time Clock
+//                This test creates a thread, starts the scheduler and
+//                delays for a time of about 5 seconds.  This test should
+//                be expected to run for about this length of time.
+// Omissions:
+//     Doesn't test alarms attached to RTC.
+// Assumptions:
+//     CYGVAR_KERNEL_COUNTERS_CLOCK must be set.
+//     Resolution of clock small compared with 5s.
+//     Overhead small compared with 5s.
+// Options:
+//     CYGIMP_KERNEL_COUNTERS_SINGLE_LIST
+//     CYGIMP_KERNEL_COUNTERS_MULTI_LIST
+//     CYGVAR_KERNEL_COUNTERS_CLOCK
+//     CYGNUM_KERNEL_COUNTERS_MULTI_LIST_SIZE
