    15 AlarmServer is used to set alarms such as clock or calendar applications.

    16 The Alarm Server manages a queue of alarms and notifies the user in conjunction

    17 with other Application Framework components. </p> <p>The AlarmServer maintains

    18 the queue of all system-wide alarms, this is known as Alarm handling. Session

    19 alarms are for a single session only and are completed when an alarm expires.

    20 Non session alarms occur if a session orphans its alarm by closing its connection

    21 to the AlarmServer. </p> </section>

    23 applications that require Chinese date support calcon is a calendar conversion

    24 utility which provides conversion between Gregorian and Chinese Lunar calendar

    25 dates. The conversion is restricted to date conversion – time conversion is

    26 not supported. Corrections have been applied where Chinese lunar days are

    27 deemed to start at times other than midnight. </p> <p>Julian dates are used

    28 for internal storage. A Julian date is a count of days from a point in time

    29 (defined as noon 24/11/4713 BC). Chinese Lunar calendar dates consist of: </p> <ul>

    39 enables the user to search for specific information on a help database. Help

    40 databases contain rich text formatted data (including pictures) and metadata

    41 used to identify help information for searching. </p> <p>The help launcher

    42 is a small DLL that allows the device-specific help application to be launched

    43 with a context sensitive identifier, so that a suitable help topic is displayed

    44 within the help application. </p> </section>

    46 Zone Server provides functionality to convert between UTC times and local

    47 “wall-clock” times. It allows for Daylight Savings Time (DST) rules and adjusts

    48 local times accordingly. This functionality applies to both the current locale

    49 and other specified locales. It also applies to any time, historical or future

    50 (within a given range) at the specified locale </p> <p>The application allows

    51 time conversion between UTC and local “wall-clock” time and automatic clock

    52 adjustment for daylight saving. </p> <p>The Time Zone Compiler creates a Time

    53 Zone Database for Symbian OS from the Olson Tz database, which provides a

    54 collaborative compilation of information about the world's time zones. </p> </section>

    56 Time Zone Localization component provides localisation support for time zone

    57 names. The component makes use of the standard Symbian OS resource framework

    58 for loading localizable strings. This allows licensees to provide localized

    59 time zone and city name strings for target markets. </p> <p>Localizable text

    72 Versit component provides a set of classes that can be used by application

    73 or system developers to import and export data. The data is formatted according

    74 to a set of standards initially defined by the Versit consortium. </p> <p>The

    75 plain-text formatted data can be included in emails, saved to disk or transferred

    76 from one application to another using streams. Two specifications have been

    77 published: vCard for the transmission of contact information and vCal for

    78 the transmission of calendaring information. </p> <p>Although the information

    79 contained in contact data is different from that contained in calendar data,

    80 the basic formatting of the information follows the same style. It is this

    81 formatting style that has had a strong influence on the functional requirements

    82 of the Versit component. </p> </section>
