Daylight Saving Time Changes

Daylight Saving Time in the U.S. and Canada has been extended by three weeks in the spring and one week in the fall. This will affect some messages sent out by GroupWise or any other collaboration email system. Appointments and other scheduled events sent out before workstations received the updated DST time zone changes may be off by one hour during the period from March 11-31 and also from October 28 to November 4.

We want to make you aware of the need to check your own calendar for appointment accuracy. There is also one change required to reset your Scheduled Work Start and End times in GroupWise.

Scheduled events, appointments, meetings, posted events made for the time period between the old and new DST transition dates could be off by one hour. For example, an appointment scheduled to occur between March 11 and April 1, 2007 (the new and old DST start dates), will be scheduled at the wrong time because the wrong DST information was used to schedule the event. This will only be noticed after the workstation is updated with the new DST time zone definitions.

This behavior also applies to appointments scheduled to occur between October 28 and November 4 of 2007 (the old and new DST end dates), or during any similar period in future years. After a workstation's time zone definitions are updated, appointments can be correctly scheduled for these time periods.

Work Schedule Start and End times will be shown off by one hour during the extended DST periods after the workstation has been updated with the new DST time zone definitions. Before Mar 11, 2007 and after Mar 31, 2007 they will be correct when viewed in a Calendar view. Between Mar 11 and 31, 2007 they will be off by one hour in any time zone that has had changed DST definitions. The same will be seen when looking at the week between Oct 28 and Nov 4, 2007.

Busy Search results show users Start and End Work Schedule times off by one hour during new DST time zone definition periods.

All end users should review their scheduled events and adjust them as needed after the tool has been run. End users should complete the following tasks after the workstation(s) have been updated with the new DST time zone changes.
