NKSP. However when calculating time differences between two time |

195 |

stamp is based on the script's actual CPU execution time. So the |

internal clock which is used for generating such time stamps is only |
197 |
|
running forward if the respective script is actually executed by the |
198 |

CPU. Whenever your script is not really executed by the CPU (i.e. because |

your script got suspended by a wait() call or got forcely suspended due to |

real-time constraints, or when the entire sampler application got suspended |
