// 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
