.ICS file showing 1 hour different in time when save that file

I have a program that sends calendar appointments out to users. However these users are in many different time zones. When I create the .ics file, I have create time in GMT timezone, because our server timezone is GMT. They then get sent out to the users, who are scattered across many time zones. They are receiving 1 hour different time when they saving .ics file.

For example i scheduled appointment of 11:30 - 12:30 on 8th Aug it is showing 12:30 - 13:30 on 8th Aug.

My ICS code is here:

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//test.com//NONSGML kigkonsult.se iCalcreator 2.18//

X-WR-TIMEZONE:Europe/London

Since 11:30 UTC is 12:30 British Summer Time, I strongly suspect there is no problem here. The UTC time in your invitation is unambiguous. Your calendar application knows your time zone, and has displayed the meeting in your local (daylight saving) time. People receiving the same invitation in Tokyo and Sydney will see the meeting displayed in their local timezone also.

You define your timezone to be "Europe/London" which uses daylight savings and you define the DTSTART/DTEND in UTC wich has no daylight savings.
