The support for a custom stop signal was mainly implemented to be used with this timer - if the SimpleTimer is used for other purposes than simulation, then it might be undesired that the simulation's stop signal can stop this timer. To stop multiple running SimpleTimers at once, it might still be in the user's interest to use a stop signal (differing from the one used in the simulation).

Simulated time refers to a fictional measure of time, that is not related to the unix time of the physical devices on which the different tasks operate. Instead, the current time is determined by a central timing instance, in this case by the LCC. Simulated time can be used to speed up or slow down the simulation of a scenario, which might help to detect errors, to improve the timing of the individual components or to test faster how the system operates on the long run.
