Global IP Office Technical Tip
164: IP Office and New Daylight Saving Time in the United States and
*Release Date: 9 March 2007
Starting in March 2007, Daylight Saving Time (DST) in the United States and Canada will begin on the second Sunday in March and end on the first Sunday in November.
If the IP Office is configured to use a Time Server running on Microsoft Windows, an update to cater for the DST changes was released by Microsoft through Microsoft/Windows Update in February.
In certain circumstances on IP Office systems running 3.x software which have the Time of Day “TmDay” button programmed on phones, that clock may fail to update correctly.
This issue is resolved in the 3.2 Q1 2007 Maintenance Release.
