I'm pretty sure you can't change the time and still hope that the events will follow along with it. The only events that I think will change if you play around with the time is the time of day and maybe the daily events including shops, battles etc.. What wont happen is the change of mirage spots and stuff like that. By changing the time, the duration to wait increase. So, I think there's no way to safely change the time and still manage to recieve all the time details. All I could say is, WAIT!
Hope this helped!
