[evolution-patches] A patch for calendar based on trunk

[Kidd Wang <kidd wang sun com>]

Hi,

This patch is aimed for trunk. We have found a bug in calendar which can 
be reproduced as follows:
1.Invoke your evolution
2.Create a new All-day event somewhere, for example, in 12/25
3.Print preview it
4.Save and close it
5.Froward it as iCalendar
6.Explore the message with calendar information
Actual result:
After #3,the time of appointment is from 12/25 8:00 to 12/26 8:00.
After #6,you will see that the start time is 12/25 and the end time is 
12/26en.

I guess that's because of the invalid time zone and enclosed is a patch 
to fix that. Would you like to spend a little time to review it?

Best regards
