The standard dates for North American Daylight Saving Time (DST) change in March 2007. Previously, DST began on the first Sunday in April and ended on the last Sunday in October. As of March 2007, DST begins on the second Sunday in March and ends on the first Sunday in November.
When the DST dates change in March 2007, BlackBerry devices will not update their clocks for the affected time zones if no patches for impacted BlackBerry software and third party software are applied. As a result, your BlackBerry device might not display correct time zone information for certain time periods during the year.
This patch installs Daylight Saving Time (DST) on your BlackBerry device.
