But this is correct, the UTC times are different because you are in a
different "time zone" when you are in daylight savings mode. When the mail
client uses the operating system to translate from local time to UTC it
takes into consideration daylight savings time. 

So in South Africa(UTC+0200) I can watch the web cast in winter at 10:30 and
summer at 9:30. You will see the web cast in the winter (UTC+0100) at 9:30
and in summer (UTC+0200) 9:30. So without knowing anything about your
daylight savings time I will know exactly when the web cast will take place
in any part of the world.
