I'm using Google Apps Standard Edition, however, I noticed the same exact behavior with my Gmail account as well. At first I thought that reminders are sent at odd times for all-day events, but then I found out that they are supposed to be sent at 12AM.I created 3 reminders with an email reminder set to 0 minutes. Here are the results of when I received the email:For the event at 7/15/10 04:00 PM, the reminder was sent on 7/15/10 04:00 PMFor the event at 7/16/10 12:00 AM, the reminder was sent on 7/16/10 12:00 AMFor the event at 7/16/10 All-day event, the reminder was sent on 7/15/10 05:00 PM (Incorrect)These are the email headers for the last event's reminder:Received: [...] Thu, 15 Jul 2010 17:00:58 -0700 (PDT)Date: Fri, 16 Jul 2010 00:00:58 +0000Subject: Reminder: Test @ Fri Jul 16, 2010 It seems that the 0 minute offset is from UTC instead of my time zone (PDT).These are the settings that I have set, for both calendars:Google Apps > Domain Settings > General > Time Zone:Default time zone for users at [your domain]: (GMT-08:00) Pacific TimeGoogle Calendar > Calendar Settings > General:Your current time zone: (GMT-08:00) Pacific TimeGoogle Calendar > Calendar Settings > Calendars > [My Calendar] > Calendar Details:Calendar Time Zone: This calendar uses your current time zone:   (GMT-08:00) Pacific TimeOther things that I have tried which didn't work:Creating a new calendar.Creating a new Google Apps user.Any idea what I'm doing wrong and how to fix this?
