+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>
