//
// Author(s): dsm
// Contributors: dsm
// Date: 1998-03-20
// 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
