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 PM
  • For the event at 7/16/10 12:00 AM, the reminder was sent on 7/16/10 12:00 AM
  • For 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 +0000
Subject: 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 Time
  • Google Calendar > Calendar Settings > General:
    • Your current time zone: (GMT-08:00) Pacific Time
  • Google Calendar > Calendar Settings > Calendars > [My Calendar] > Calendar Details:
    • Calendar Time Zone: This calendar uses your current time zone: (GMT-08:00) Pacific Time

Other 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?

I've set an email for an event tomorrow in Europe/London time (currently UTC+1) and will see if I can reproduce this... – Jon Skeet Jul 17 '10 at 6:32
@Jon: Thanks... – Senseful Jul 17 '10 at 7:29
Aargh, I'm not sure I ever got the email. Will double check. Doh. – Jon Skeet Jul 30 '10 at 6:42
