	Timer - Wikipedia, the free encyclopedia
		Timers can be mechanical, electromechanical, digital, or even software, since most computers have clocks.
		Early mechanical timers used typical clockwork mechanisms, such as an escapement and spring to regulate their speed.
		Another type of electromechanical timer (a cam timer) uses a small synchronous AC motor turning a cam against a comb of switch contacts.

	Timer (Java 2 Platform SE v1.4.2)
		Creates a new timer whose associated thread may be specified to run as a daemon.
		A deamon thread is called for if the timer will be used to schedule repeating "maintenance activities", which must be performed as long as the application is running, but should not prolong the lifetime of the application.
		Note that calling this method from within the run method of a timer task that was invoked by this timer absolutely guarantees that the ongoing task execution is the last task execution that will ever be performed by this timer.

	Timer Class
		This timer is optimized for use in Windows Forms applications and must be used in a window.
		This Windows timer is designed for a single-threaded environment where UI threads are used to perform processing.
		When using this timer, use the Tick event to perform a polling operation or to display a splash screen for a specified amount of time.

	Guidelines For Providing Multimedia Timer Support
		System timers are the timers used by the operating system to perform core tasks such as tracking the time of day and triggering time-based events.
		Timer objects are used by the system to track deadlines and to signal applications when a deadline is reached.
		Timer objects are checked at each clock interrupt to see if the time the object was supposed to expire has passed and schedule a timer DPC to generate a signal or run code for each object that has expired.

		The timer delegate is specified when the timer is constructed, and cannot be changed.
		When you create a timer, you can specify an amount of time to wait before the first execution of the method (due time), and an amount of time to wait between subsequent executions (period).
		When a timer is no longer needed, use the Dispose method to free the resources held by the timer.

	Help: TIMER
		The TIMER command accepts its parameters in any order, and acts on the specified one of three possible timers (system stopwatches) by turning it on or off, or by displaying its current elapsed time.
		The TIMER command with neither of the keywords ON and OFF nor the /S option toggles the state of the timer.
		The smallest interval TIMER can measure depends on the operating system you are using, your hardware, and the interaction between the two.

	MFC Controls - Timers
		A timer is a non-spatial object that uses recurring lapses of time from a computer or from your application.
		As opposed to the time set on your computer, a timer is partly but greatly under your control.
		Unlike most other controls, the MFC timer has neither a button to represent it nor a class.

	555 Timer/Oscillator Tutorial
		This timer uses a maze of transistors, diodes and resistors and for this complex reason I will use a more simplified (but accurate) block diagram to explain the internal organizations of the 555.
		The 556 timer is a dual 555 version and comes in a 14-pin DIP package, the 558 is a quad version with four 555's also in a 14 pin DIP case.
		Thus, when the timer is driven in the monostable mode with input pulses longer than the desired output pulse width, the input trigger should effectively be shortened by differentiation.

	How To Use a Waitable Timer with an Asynchronous Procedure Call
		A waitable timer is a kernel object that is signaled at a certain time or at regular intervals.
		If a periodic timer is required, you should create the timer as an auto-reset timer by passing FALSE as the second parameter to CreateWaitableTimer().
		When you are using a waitable timer with an APC, the thread that sets the timer SHOULD NOT wait on the handle of the timer.

	flash.utils.Timer (Flex™ 2 Language Reference)
		The Timer class is the interface to Flash Player timers.
		For example, if a SWF file is set to play at 10 frames per second [fps], which is 100 millisecond intervals, but your timer is set to fire an event at 80 milliseconds, Flash Player will fire the event close to the 100 millisecond interval.
		If the timer has been reset, only the fires since the reset are counted.

	Timer ( timer )
		When f is called in main, the timer is in the state stopped.
		In a recursive call the counter is incremented at the beginning and decremented upon termination, but the timer remains in the state running.
		Only when the top-level call of f terminates and returns to main, the counter is decremented from one to zero, which puts the timer into the state stopped.

		The Timer component is a server-based timer, which allows you to specify a recurring interval at which the Elapsed event is raised in your application.
		The server-based Timer is designed for use with worker threads in a multithreaded environment.
		The Timer component raises the Elapsed event, based on the value of the Interval property.

	Timer Class (System.Threading)
		As long as you are using a Timer, you must keep a reference to it.
		To receive a signal when the timer is disposed, use the Dispose(WaitHandle) method overload that takes a WaitHandle.
		The callback can be executed simultaneously on two thread pool threads if the timer interval is less than the time required to execute the callback, or if all thread pool threads are in use and the callback is queued multiple times.

	How to Use Swing Timers (The Java™ Tutorials > Creating a GUI with JFC/Swing > Using Other Swing Features)
		In general, we recommend using Swing timers rather than general-purpose timers for GUI-related tasks because Swing timers all share the same, pre-existing timer thread and the GUI-related task automatically executes on the event-dispatching thread.
		When you create the timer, you specify an action listener to be notified when the timer "goes off".
		Note that all timers ahre the same thread so there is no risk of Swing timers spawning more threads than the user's system can handle.

	Tip Of The Month: Timer Issues And Tips
		Your application will not receive the timer events immediately, because it requires the kernel to switch execution to your application’s thread, and there may be other threads to be served before yours; thus you will not be able to handle the event immediately.
		This is logical, because the At-timers are set to stop on a specific date and time - the timer cannot be kept running anymore because the set time may no longer be valid or desirable, so the timer passes the decision making to whoever started the timer.
		With interval timers the changes in system time are not usually an issue, unless you are expecting the interval timer to complete on a specific date and time - which would be a poor design because the system time may change while the timer is running.
