+// Description:
+// e32test\system\t_mstim.cpp
+// Overview:
+// Test millisecond timers
+// API Information:
+// NTimer
+// Details:
+// - Create and start a number of periodic timers, verify results are
+// as expected.
+// - Attempt to start a timer that has already been started. Verify returned
+// error results.
+// - Start one shot interrupt and one shot DFC timers and verify that the 
+// delay time is correct.
+// - Start additional one shot interrupt timers with various values and verify
+// results are as expected.
+// - Calculate and print the elapsed time.
+// - Start some timers, display min. max, avg and count information on each.
+// Verify results are as expected.
+// - Cancel a periodic timer and reuse it in a variety of conditions. Time how
+// long it takes for each to complete.
+// - Perform some random timer tests and display the results.
+// - Check idle time while a variety of one shot timers run. Verify results are
+// within the expected range.
+// Platforms/Drives/Compatibility:
+// All.
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
