I fixed the VEvent generating service to take time zones into account. Download the source code here or you can use mine, but I can't guarantee it is always going to be working.
Here is an example of how to use it to create a link for Cabana Night:
1. Go to CreateVEventUrl.aspx Page
2. Enter start date 10/6/2004
3. Enter start time 6:00
4. Choose PM from AM/PM listing
5. Choose Eastern Time (US & Canada) for the Time Zone
6. Enter 120 for Duration in Minutes
7. Leave Priority listing choice at low
8. Enter "Microsoft Waltham, MA" for Location
9. Enter "Cabana Night" for Subject
10. For the Description, enter something like For more information see: http://weblogs.asp.net/trobbins/archive/2004/08/29/222431.aspx
11. Click the Generate button
12. Copy the text out of the URL text box and use it to create your link. For example:
VEvent.aspx?sd=10/6/2004&t=1080&dur=120&s=Cabana+Night&d=For+more+information+see%3a+http%3a%2f%2fweblogs.asp.net%2ftrobbins%2farchive%2f2004%2f08%2f29%2f222431.aspx&p=-1&l=Microsoft+Waltham%2c+MA&tz=-5%3a00 will create a like like this
(HTML code looks like this: <A href="http://www.jasonhaley.com/services/VEvent.aspx?sd=10/6/2004&t=1080&dur=120&s=Cabana+Night&d=For+more+information+see%3a+http%3a%2f%2fweblogs.asp.net%2ftrobbins%2farchive%2f2004%2f08%2f29%2f222431.aspx&p=-1&l=Microsoft+Waltham%2c+MA&tz=-5%3a00">this</A>)
The only drawback is that you are limited to a total of 255 characters in your querystring. Next thing I'll probably do is add a character count onto the generating page so you know how close you are to the max number of characters.
Now I won't have to add all these links to the calender, save them as vcs files, move them to the web site, and then create a link to them...
