// 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
