// Description:
// e32test\active\t_ctimer.cpp
// Overview:
// Test timer functionality.
// API Information:
// CTimer 
// Details:
// - Create some timer active objects, install an active scheduler, and the
// active objects, request event after an interval and verify that:
// - Absolute timer set with time less than current time return KErrUnderflow.
// - Relative timer set with 0 goes off immediately.
// - Absolute timer set to a time of now returns KErrUnderflow.
// - Absolute timer set with time more than the current time returns KErrNone.
// - Repeated timer is cancelled as expected.
// - Call relative timer's After function without adding it to the active scheduler 
// and check for panic.
// - Call absolute timer's At function without adding it to the active scheduler and 
// check for panic.
// - Check if heap has been corrupted by the tests.
// Platforms/Drives/Compatibility:
// All.
// Assumptions/Requirement/Pre-requisites:
// Failures and causes:
// Base Port information:
//
