Detailed Description

Mathematic type that represent a set of pseudo-real-number (in the unit of time), such as [-1s, +1s] U [+2, +5s].

Allows to query if a specific time-point or time-interval is contained in this set

Warning: Unlike MTime, Maya represent the time in MTimeRange with an 64-bits signed integer (ticks) (1 tick == 1/6000 second). The time you can represent in this range is [0.167 milliseconds, 48 million-years). For times smaller than 1 tick, Maya will round it to the closest tick. For times greater than 2^62 ticks, Maya may consider them as 'infinity' and arithmetic rules may not work properly. For times greater than 2^63 ticks, result are overflowed and any use of them are undefined behavior.

Examples:: simplePhysicsEngine/simplePhysicsEngine.cpp, and simpleSimulationNode/simpleSimulationNode.cpp.
