Avaya Communication Manager

Methods For Updating Daylight Saving Time Rules

Several localities worldwide have already extended their Daylight Saving Time (DST) rules or will do so in the future. Avaya Communication Manager can automatically adjust for Daylight Saving Time, based on the built-in rules for Daylight Saving Time for each locality. If there is a change in these rules for a particular locality, Avaya Communication Manager may require software updates.

There are three methods for handling new Daylight Saving Time rules. The availability and appropriateness of each method for a given system depends on that system’s release and locality.

1.     Recent releases of Communication Manager have new Daylight Saving Time rules built into the software.

2.     Patches – Some older releases do not have the rules built into the software. In many of those cases, patches are available to handle the new rules. These patches may be applied in addition to a patch already on the system.

3.     Manual procedures - In some cases, Communication Manager updates (i.e., patch or new release) may not be available soon enough to accommodate support of changing Daylight Saving Time start and end dates. In those cases, manual procedures must be followed.
