note: it uses Zulu Time (GMT/UTC).. The client will take this time and using its own TZ settings display the correct date/time for that user.

Thanks ve3ofa,

That doesn't really help solve my problem. How would I convert my existing datetime to UTC time?

The DateTime object in .net doesn't take into account the timezone, so how would I convert 8:30 AM EST to UTC and also taking into account daylight savings time?

Wouldn't it be easier if the vCalendar can be set to a timezone?

Attached is my code that generates the vCalendar file, I've tried adding the TimeZone block but it doesn't seem to work.
TimeZoneCode.txt

you need to use another .net item convertdatetimetoutc(datetime())

Thanks ve3ofa,

But that still doesn't answer my question as to whether or not I can set a timezone in the vCanlendar file.

I was able to figure this out on my own and added the following to the file to make it work:

BEGIN:VTIMEZONE
...
...
END:VTIMEZONE

Outlook will NEVER use anything other that UTC. http://cc.oulu.fi/~jarioksa/ical/icaloutlook.html

Figured out solution on my own
