Time Management in The High Level Architecture

Time management is required in simulations to ensure that temporal aspects of the system un der investigation are correctly reproduced by the simulation model. This paper describes the time management services that have been de fined in the High Level Architecture. The need for time management services is discussed, as well as design rationales that lead to the current definition of the HLA time management ser vices. These services are described, highlighting information that must flow between federates and the Runtime Infrastructure (RTI) software in order to efficiently implement time manage ment algorithms.
