Calendar Time Zone


K

Kate Townsend

We have a user with the following calendar issue. For three weeks in March
2007, her calendar entries are off by one hour (they are listed as occuring
one hour later than they should be). However, other users who have
permission to view her calendar see the events listed at the proper time.
We tried deleting the items and recreating them in the proper time slot, but
other users then see the entry an hour earlier.

The rest of her calendar seems to be fine.

Do you have any ideas how I can correct this?

Thank you in advance for any help.

This is just a stab in the dark - but March is the month we switch to
Daylight Savings (or from it?), therefore I would say to check out your
'Date and Time' propertise in the Control Panel.

On the Time Zone tab make sure 'automatically adjust clock for daylight
saving changes' is checked. And check the rest of the options like date &
time, timezone etc ehich your there.

That sounds more convincing than my answer - especially because of the 3
week part.

I have something similar to this. Before applying kb928388, all
appointments showed correctly, even during the weeks in March, October
and November. After applying this fix to the client, appointments
during those times are now an hour late.

It appears that the fix actually created an issue in this case. This
also appears to be what the original issue was in this thread. Anyone
know of a way to correct it?

I've confirmed and reported issues to Microsoft in my environment with the
Microsoft 928388 Daylight savings patch and Outlook 2003 appointments, where
they appear time shifted one hour, when viewed on a computer with Outlook
2003 with the patch and a computer with Office 2003 without the patch. The
same is true when viewing appointments on Outlook 2003 with the patch and
Outlook XP (regardless of patch level).

Appointments appear offset by an hour for the time period in March affected
by the advance in daylight savings time, but I suspect more issues to be at
play, and I'm still looking into this. I would suggest holding off any
further deployment and closely monitoring this issue before continuing (which
I would put off as long as is necessary, or at least until Microsoft comes
clean with full ramifications and a warning, or better yet, pulling the patch
and releasing one without these effects).

A quick test would be to create items and view the same mailbox calendar
during the DST "adjustment" period, March 11 to April 1, 2007, and you'll
also see differences between Outlook XP and and Outlook 2003 client on
patched Windows XP machines. There is no Windows 2000 patch I'm yet aware of,
so I couldn't test that OS scenario.

To err on the side of caution, all clients connecting to the same mailbox
should be on the same Office Version AND the same patch level to view correct
appointment times, and all clients connecting to the same mailbox should all
be updated at the same time.

As a sidenote, the Exchange Server Message Store contains calendar items in
Zulu/UTC time, and I believe time translation is done at the client level,
within the OS (hence the effect of the patch) and can also be done within
Outlook's time zone setting option (which may prove to need its own patch).
This is how you can have clients connecting to Exchange Servers in different
time zones and still display local time correctly.

I'm been made aware of a tool Microsoft is developing to run against the
desktop Outlook client to correct daylight savings time appointment issues. I
understand this tool will be similar to a new feature contained within
Outlook 2007. The Calendar item I'm seeing seems specific to Outlook 2003 AND
the Windows XP 928338 patch, and not to Outlook XP regardless of the patch.
However, I can't see how a tool would work, given the confusion some of us
are seeing when appointments are changed by several people, on different
Outlook versions, and on computers with and without the 928388 patch.

Blackberry device calendars and their impact upon Outlook also seem to be
affected to a different degree, and RIM informed me they are working on a
patch, expected in late January. I wonder how/if Windows Mobile is affected,
and what impact the 928388 patch may have upon those client's Outlook
clients' and calendar syncing.

For now, I'm advising all my clients to type the time of the appointment
into the appointment subject line.

Thanks,

Microsoft is saying that customers should wait and deploy the Outlook
Data Update tool and the OS DST 2007 patches at the same time. As fara
as unsupported OSes go (such as Windows 2000), there is a tool
available at www.sharpebusinesssolutions.com/dst2007.htm that can
handle the DST 2007 changes for all major versions of client and
server-side Windows operating systems.

I need to add, in all fairness to Microsoft, that is issue is much more than
just a calendar problem. Daylight Saving Time(DST) changes for 2007 are
impacting much more that a calendar. Just take a look at all these vendor
links for updates. There are so many patches, I wonder if we'll all be done
in time....http://www.dstinfo.com/site/2007/01/vendor_links_1.html
