Timers

Absolute and elapsed timers

System target files that support the real-time model (rtModel) data structure provide efficient time computation services for blocks that request absolute or elapsed time. Absolute time is the time interval from the start of program execution to the time when the function that includes code for a block that uses absolute time starts executing. Elapsed time is the time interval between two consecutive executions of a block. See Timer Representation and Computation for more information about how the code generator represents and uses timers.
