He :)
All places where time(NULL) is used to measure some time interval could
easily be changed to use monotonic cTimeMs.
But with timers current wall clock time is really required ...
It might be enough to replace most of time(NULL) 's with something like
time_t cTimeMs::Time(void) {
return (time_t)(cTimeMs::Now() / 1000);
}
Using the cTimeMs timer/trigger mechanism requires some more changes and
debugging.
