Time zone of Exchange server-- how to retrieve via WebDav?

DALindsey · Joined: 25 Feb 2008 Posts: 1

When I retrieve meetings, etc from Exchange using WebDav, I know the
time is returned in UTC. My question is how do I access the time zone
of the Exchange server so I then can convert the appointment from UTC
to the proper timezone?

In my webdav request, I do ask for the timezoneid property (I also
tried the timezone property) but it is returned as "".

Sample request:

PROPFIND /exchange/test/Calendar/21.EML HTTP/1.1
Content-Type: text/xml
Host: 9.33.36.65
Depth: 1
Authorization: Basic Y3BwXHRlc3Q6UGFzc3cwcmQ=
User-Agent: Java/1.4.2
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
Content-Length: 461

This is an allday event that was created in the +1:00 timezone...so is
stored in Exchange an hour behind. Note that the timezoneid is empty..

Any assistance would be appreciated. Thanks!

Hello,

the server timezone is irrelevant to the meeting. Most of the time
information of a contact is stored as UTC. Therefore you can use the .NET
DateTime.ToLocalTime.

This usually makes the most sense on a client computer.

But don't forget to call DateTime.ToUniversalTime before you save something
to the store.

Kind regards,
Henning Krause
