// *****************************************************************************
//
// CLASS DESCRIPTION (MTime)
//
// The MTime class provides a fundamental type for the Maya API to hold and
// manipulate animation timing information in various unit systems. All
// API methods that require or return timing information do so through
// variables of this type.
//
// If one desires to manipulate time in such a way that integer changes in
// an MTime instance result in integer changes in the frame displayed by
// the timeslider, then an MTime instance should be created that uses UI
// units. This can be done either by using the default constructor, or by
// passing the return value of the static method uiUnit to the normal
// constructor. Once such an MTime instance is created, its value will be
// equivalent to a frame on the timeslider.
//
// It should be noted that while the timeslider displays frames, a
// seemingly unitless value, Maya internally is operating based on the
// desired frameRate (one of those specified by the MTime::Unit enum. It
// is necessary for the API programmer to be aware of this as MTime
// instances are not unitless and allow the manipulation of time in any
// desired units.
