-<section><title>Description</title> <p>This example code first connects to
-the time zone server (class <xref href="GUID-052221AD-916E-3E47-9510-AC0495A19A70.dita"><apiname>RTz</apiname></xref>). Then it uses <xref href="GUID-052221AD-916E-3E47-9510-AC0495A19A70.dita#GUID-052221AD-916E-3E47-9510-AC0495A19A70/GUID-A7D33D36-8AA5-3775-B4B8-36C30EF88DB0"><apiname>RTz::ConvertToLocalTime()</apiname></xref> to
-convert a UTC time to local time. The time to convert and the time zone to
-convert it to are randomly chosen. This demonstrates that the time zone server
-can convert any time, past, present or future, for any time zone, as long
-as a rule exists for the conversion. Conversion rules are stored in a native
-Symbian OS database that is a compressed form of the Olson time zone database
-(<xref href="http://www.twinsun.com/tz/tz-link.htm" scope="external">http://www.twinsun.com/tz/tz-link.htm</xref>).
-The database can be configured by phone manufacturers to save space. </p> <p>The
-example then converts the current local time for the system time zone to the
-current local time for a different time zone. This is a two stage process.
-First, the local time is converted to UTC using <xref href="GUID-052221AD-916E-3E47-9510-AC0495A19A70.dita#GUID-052221AD-916E-3E47-9510-AC0495A19A70/GUID-645162AA-631E-3125-A002-82EB8D91DB08"><apiname>RTz::ConvertToUniversalTime()</apiname></xref>.
-When converting between local and UTC times for the current system time zone,
-there is no need to specify the time zone ID. Then UTC is converted to local
-time for the other time zone. Before the example terminates, the connection
-to the server is closed. </p> <p>No special capabilities are needed to do
-time zone conversion. </p> <p>Class <xref href="GUID-0B5453C5-76A2-31B2-A32C-2CDC1F3367CE.dita"><apiname>CTzId</apiname></xref> identifies a
-time zone. It stores the identifier either as text, (for instance Australia/Sydney),
-or as a number. Numeric time zone IDs are assigned by the phone manufacturer,
-so can vary from phone to phone. </p> <p>For efficiency, the time zone server
-caches a copy of a range of conversion rules for the current time zone. These
-cached rules are <i>actualised</i>, meaning they have been expanded from the
-encoded compact format as stored in the database, so are quicker to access. </p> <p>Class <xref href="GUID-37A4A4ED-FFF8-3C98-B028-EA1947EA7BEF.dita"><apiname>CTzConverter</apiname></xref>,
-which is not used in this example, provides an alternative conversion API
-to <xref href="GUID-052221AD-916E-3E47-9510-AC0495A19A70.dita"><apiname>RTz</apiname></xref>. It caches 5 years' worth of conversion rules for
-a specific time zone (either the time zone specified in the conversion function,
-or the system time zone), on the client side, so avoiding the need for an
-an IPC call for each conversion. <codeph>CTzConverter</codeph> is more efficient
-than <codeph>RTz</codeph> when doing multiple conversions for a single time
-zone. </p> </section>
-<section><title>Usage</title><p> This is a console application, so does not
-have a GUI. It builds an executable called<filepath> TZExample.exe</filepath> in
-the standard location (<filepath>\epoc32\release\winscw\&lt;build_variant&gt;</filepath> for
-CodeWarrior). After launching the executable, depending on the emulator you
-are using, you may need to task away from the app launcher/shell screen to
