If you do use the system clock adjustment, it will give you less events. That is unless you are only forwarding a few hours a day. If you adjust your clock forward more then 24 hours you will get less. That is because you will only get one event at a time. So if you advance your clock three days you will still only get one event. But if you don’t advance it you will get (on average) one event for each of those three days. Does that make sense?
