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.
