Beginning in 2007, the start and end date of Daylight Savings Time (DST) will change in the United States (see http://aa.usno.navy.mil/faq/docs/daylight_time.html). Daylight Savings Time will begin March 11, 2007 (the second Sunday in March) instead of April 1 (the first Sunday of April). Daylight Savings Time will end November 4, 2007 (the first Sunday of November) instead of October 28 (the last Sunday in October).

Collage uses Java technology on the server as well as on the clients. To successfully support the 2007 DST changes, the Java software will need to be upgraded (see http://java.sun.com/developer/technicalArticles/Intl/USDST/) on the client machines and the Collage server. For complete details on how Collage will be affected without these changes, see Alert A15

IMPORTANT: There may also be operating system patches that need to be applied to both the client and the server. Check with the appropriate vendors for details. Also, a large number of the dates in Collage are retrieved using function calls to the database. Because of this, make sure the appropriate operating system patches are also applied to the server hosting the Collage database.

********************************************************************************************************************************************
IMPORTANT: Instructions in this document only apply to Collage 5.1.0.x and 5.1.1.x. Instructions for Collage 4.6.x are available in Alert A17. Collage 5.1.2 and later don't need updates.
