As the title perfectly describes, sometimes although calendar shows the appointment at the right time, it alerts me 1 hour later than it should. And that's not always the case. I should notice better, but I think it happens at the 11pm-12am range. Is it because it's "confused" with the time change from pm->am? My time zones are NOT set automatically, and they are correctly set to Athens (both in mail-calendar settings and date× settings). I googled the problem, and people said that time zones would fix it, but mine are correct already. Any help is much appreciated. PS: It's a 3gs 32gb, jailbroken at 4.3.3 (8J2) and firmware 05.16.02.
