Help: Implementing Wave's FPS and DeltaTime

If anyone cares, here is Wave's DeltaTime code, documented a bit more concisely (in my opinion):

Type Delta
	'Delta Time code provided by Truplos@....
	Global DeltaTime#
	Global TimeDelay%
	Function Start()
		'Call Delta.Start() before main loop
		TimeDelay = MilliSecs()
	End Function
	Function Time#()
		'EXAMPLE:
		'use this:         	 Speed:+ 10*Delta.Time()
		'instead of this:   Speed:+ 10
		'A value of 10 now means 10 per second!  Not 10 per frame!
		'Note: Variables (speed in this example) that get multiplied by Delta.Time() MUST be declared as a float!
		Return DeltaTime#
	End Function
	Function Update()
		'Call Delta.Update() once in the main loop.
		DeltaTime = ( MilliSecs()- TimeDelay )*0.001
		TimeDelay = MilliSecs()
	EndFunction
End Type
