I’ve created an iCal feed for a calendar on a website. The date/time in the markup is correct but when I try to subscribe to it, all the times are offset -5 hours, which is the same as the time zone offset. Here’s an example with a single event:
BEGIN:VCALENDAR

The time specified here, 10:00AM, is correct but after importing it becomes 5:00AM. What am I doing wrong?
