Timezones not working for calendar event

I am having difficulties with timezones in an event. This is the contents of the event, and it's specifying the event with a TZID. I am being told however that when people in Central timezone add it, it appears as 2PM rather then intended 1PM. I am in ET so not able to test this.

Do you know why it would be happening?

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//http://XXX//Event
METHOD:PUBLISH
BEGIN:VEVENT
DTSTART;TZID="America/Chicago":20150811T130000
DTEND;TZID="America/Chicago":20150811T141500
SUMMARY:Test Event
DESCRIPTION:Test Event
LOCATION:Test Event Location
END:VEVENT
END:VCALENDAR

See RFC5545, Time Zone Component and Time Zone Identifier: you need to add a VTIMEZONE component to your calendar file where you definea TZID so that you can refer to it in your VEVENT.

Parameter Name: TZID

This parameter MUST be specified on the "DTSTART", "DTEND", "DUE", "EXDATE", and "RDATE" properties when either a DATE-TIME or TIME value type is specified and when the value is neither a UTC or a "floating" time. Failure to include and follow VTIMEZONE definitions in iCalendar objects may lead to inconsistent understanding of the local time at any given location.

It should be noted that while Outlook/Exchange have repeatedly been reported to not require the VTIMEZONE, failure to include a VTIMEZONE leads to unpredictable behaviour from other calendars.
