Observing 2007 U.S. changes to Daylight Savings Time

Before you start:

You must have completed the following tasks:

This task assumes that you have added and configured one or more physical formats to existing message sets. For further information see: Working with physical properties.

This task describes how to ensure that the message sets observe daylight savings time (DST) in line with the 2007 U.S. changes.

If your message sets use a named time zone that is not changing DST in line with the 2007 U.S. changes, you do not need to do anything.

If you are using a GMT-04:00, GMT-05:00, GMT-06:00, GMT-07:00, or GMT-08:00 named time zone with DST, that must observe DST in line with the 2007 U.S. changes, do the following on every computer on which the broker is running:

  1. Set the environment variable MQSI_USE_NEW_US_DST to an initial value: Y, for example.
  2. Restart the broker to use the changed DST.
