−
describes how to update System TZ Data.</p><p>A client may need to update+
−
the system time zone database as changes in existing time zone rules are introduced.+
−
An example is the recent change in DST (daylight saving time) start and end+
−
times in North America.   </p><p>If there are new time zones in the updated+
−
TZ database, the update also needs to include localization data for these+
−
time zones.   </p><p>There may also be a need to make changes to existing+
−
time zones’ localization data. Examples of this include the correction of+
−
typographic errors and reflecting city name changes. Notable city name changes+
−
include Peking to Beijing and Leningrad to Saint Petersburg.   </p><p>To update+
−
system TZ data a client must create a SIS (Symbian installation) file that+
−
contains the updated TZ database.  </p><p>Create a Symbian Installation (SIS)+
−
file that contains the updated TZ database. The SIS file may also contain+
−
TZ localization resources. To create a SIS file you need to write a PKG (package)+
−
file, which is a normal text file with the extension <codeph>.pkg</codeph>.+
−
Example content of this file is given in the following steps:</p></context>+
