Constructor.

Destructor. Calls Close() .

Retrieves the daylight saving auto-update functionality.

Closes the connection to the time zone server.

Converts a time from UTC to local (wall-clock) time for the current system time zone. If caching has been enabled by the CTzConverter class, then the conversion will be done using the cache instead of issuing a request to the server.

Converts a time from UTC to the local (wall-clock) time for the specified time zone.

Converts a local (wall-clock) time for the current system time zone, to UTC. If caching has been enabled by the CTzConverter class, then the conversion will be done using the cache instead of issuing a request to the server.

Converts a local (wall-clock) time for the specified time zone, to UTC.

Retrieves the UTC offset for an array of numeric time zone ids. The offset is written back into aOffsets.

This should not be used externally.

Retrieves the time zone rules for the current home time zone.

Retrieves the time zone rules for a specified time zone.

Tells if daylight savings are applied at the specified zone at the current time

Tells if daylight savings are applied at the specified zone at a specified time

Deletes aCity from the user added cities database table. The city is checked first to ensure it exists. Name checking is case sensitive.

Retrieves the city used to select this time zone if set. If the time zone was not originally set using a city then the default city for the time zone will be returned instead.

Reads all the user defined cities stored in the database with a matching group id. If the database is empty the returned array will contain no elements.

Reads all the user defined cities stored in the database. If the database is empty the returned array will contain no elements.

Reads all the user defined cities stored in the database that are members of the time zone referenced by aTimeZoneid. If the database is empty the returned array will contain no elements.

Retrieves a cached zone from the database. The calling function takes ownership of the returned zone

Adds aCity into the user added cities database table. The city is checked first to prevent two cities with identical names and time zones existing at the same time. Name checking is case sensitive. Cities in different time zones can have the same name.

Stores the localized time zone in the database for easy retrieval. The database keeps track of the two most recently used zones, these are updated every time a new zone is set. The zone to be replaced becomes recently used zone 1, and recently used zone 1 becomes recently used zone 2. The old recently used zone 2 is discarded.

Publish notification that the home time zone (as defined in CTzLocalizer) has been changed. This function should only be called from TimeZoneLocalization.

This should not be used externally.

Panics the TzClient or TzServer code.

Sets the configuration of the UTC Offset auto-update functionality.

Sets the system time to the given local time. Note that the standard Tz algorithm is used - in the case of an ambiguous time the first occurance of the given local wall-clock time is chosen.

An example of an ambiguous time: 01:30 wall-clock time on 31/10/2004 in the UK could map to either 01:30 BST (00:30 GMT) or 01:30 GMT, as the clocks would go back at 02:00 BST (01:00 GMT))

This should not be used externally.

Sets the UTC time and the wall-clock offset for a zone not defined in the Timezone Database.

This is useful when the client wants to specify the UTC time and the wall-clock offset explicitly rather than using time zones. This function should be used instead of User::SetUTCOffset() and User::SetUTCTimeAndOffset() .

If this function has been called the time zone server will use the value returned by User::UTCOffset() as the offset value when doing time conversions. Calling User::SetUTCOffset() may therefore cause unexpected results.

The fact that the time zone has been set to the unknown time zone is not persisted across time zone server reboots. So it may be necessary to call this function each time the time zone server is started. If persistence across reboots is desired the overload RTz::SetUnknownZoneTimeL(const TTime& aUTCTime, const TInt aUTCOffset, TBool aPersistInCenRep) should be used.

Sets the UTC time and the wall-clock offset for a zone not defined in the Timezone Database.

This is useful when the client wants to specify the UTC time and the wall-clock offset explicitly rather than using time zones. This function should be used instead of User::SetUTCOffset() and User::SetUTCTimeAndOffset() .

If this function has been called the time zone server will use the value returned by User::UTCOffset() as the offset value when doing time conversions. Calling User::SetUTCOffset() may therefore cause unexpected results.

The fact that the time zone has been set to the unknown time zone is persisted across time zone server reboots only if the aPersistInCenRep argument is set to ETrue. The desired offset however is never persisted (the value returned by User::UTCOffset() is used). So it may be necessary to call this function each time the time zone server is started.

Called by the installation observer plugin to signal the start of an (un)install log.

Called by the installation observer plugin to signal the end of an (un)install log.

Called by the installation observer plugin to signal that the rules database or the resource files have been changed.

Time zone server panic codes.

The software install observer plugin can distinguish between changes to the resource files or the rules database. This enumeration indicates the filter index that is used for the resource files and rules database filters. This enum should not be used externally.
