Avaya Aura®Communication Manager
Methods For Updating Daylight Saving Time Rules
Localities worldwide routinely adjust their Daylight Saving Time (DST) rules.
Communication Manager can automatically adjust for Daylight Saving Time based on
the built-in DST rules for each locality. The DST rules are defined by the version of
the “tzdata” Linux RPM included in the software. If there is a change in these rules
for a particular locality, Communication Manager may require software updates.
There are three methods for handling new DST rules. The availability and
appropriateness of each method for a given system depends on that system’s release
and locality.
1. Recent Communication Manager releases have DST rules that were current at
the time of release built into the software.
2. Patches – Some older releases do not have the rules built into the software.
In some cases, patches are available to handle the new rules. These patches
may be applied in addition to a patch already on the system, and supersede
the DST rules originally included in the software (if any).
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 DST start and end dates. In these cases, manual
procedures must be followed. The manual procedures may be the only option
for older Communication Manager releases which are beyond End Of
Manufacturer Support (EOMS) and do not have patches available.
Method 1: DST Rules Included in Launched Communication
Manager Releases
Recent releases of Communication Manager have DST rules that were current at the
time of release already built into the software. The following table shows the tzdata
version included in Communication Manager releases:

Tzdata Versions
Tzdata is a Linux component, or RPM, created and maintained by Red Hat, Inc. This
archive file is used by Communication Manager as part of the operating system, and
defines “time zone data” (i.e., DST rules) worldwide. As new versions of tzdata are
released by Red Hat, they are incorporated into Communication Manager. This file is
included in the upcoming release of Communication Manager, and may be included
in patches for the most recent releases being sold.
To get information about the contents of each version of tzdata, please refer to Red
Hat’s web site. Here are references to various versions of tzdata. If the links below
do not work properly, you may need to copy/paste the URL directly into your
browser.

Changes to the tzdata file are cumulative. Files are named chronologically, with the
year and a letter designation. Any higher-numbered file is more recent than a lower-
numbered file. Newer files contain the most up-to-date information, including any
current or updated information from older files. For example, 2007h contains all of
the changes in 2007f and all previous versions from 2007. 2007h also includes the
current or updated information from any file created in 2006, 2005, etc.
Following are some examples of how different countries were handled with different
tzdata versions:
United States – The 2005m version has most of the DST changes that went
into effect in March 2007. Most US locations are covered with 2005m or later.
Isolated US changes have been made to tzdata since then. For example,
changes were made in 2007h to handle updates for specific counties in
Indiana.
Canada – The 2006a and 2006g versions have the main DST changes that
went into effect in March 2007.
New Zealand – 2007f contains New Zealand’s DST updates.
Australia – 2007g contains Australia’s DST updates.
Russia – 2011h contains Russia’s DST changes for 2011
Manual Date/Time Change Instructions for
Daylight Saving Time Adjustments
Localities worldwide routinely adjust their Daylight Saving Time (DST) rules.
Communication Manager can automatically adjust for Daylight Saving Time; however,
this is based on the built-in schedule dates for Daylight Saving Time for each locality.
If there is a change in these schedules for a particular locality, Communication
Manager may require software updates.
In some cases, Communication Manager updates may not be available soon enough
to accommodate support of changing Daylight Saving Time start and end dates. The

6 October 2011, ver 4
manual procedures may be the only option for older Communication Manager
releases which are beyond End Of Manufacturer Support (EOMS) and do not have
patches available. This section provides instruction on how to manually make these
changes.
The two tables below show specific country examples of changes beginning in 2007.

The Following steps must be followed in the exact order specified to be used
as a manual procedure for servers running releases of Communication
Manager that do not have a Daylight Saving Time patch available or have
not upgraded to a release of Communication Manager with the required DST
rules:
Manual Procedure to Change Time for Start of Daylight Saving Time: 1
1. If Daylight Saving Time rules other than 0 (zero) are being used in the daylight-
savings-rules SAT form, these rules must be updated via the SAT to appropriately
reflect the new Daylight Saving Time changes/adjustments.
2. After the Daylight Saving Time start date per the new rules occurs:
a. If the Server is synchronizing to a network time server, use the
following steps to disable synchronization.
NOTE: Once synchronization with a network time server is
disabled it is possible to experience clock drift on the
Communication Manager server. Clock drift occurs when the
time on the server slowly deviates or drifts from the correct
time. If the clock drift becomes too great the server time
