How about creating a public Google Calendar for the Urgent Quests and Concerts schedule, so that we can just subscribe to it? This way nobody needs to worry about time zone conversions: Google will take care of it.

• Events: urgent quests, concerts, scheduled maintenance, and emergency maintenance.
• Reminders: end date of AC and SG scratches.

Or are there commercial use restrictions to Google Calendar? In that case, a Google Calendar-compliant .csv file would be great, so we can just import it ourselves.
