Detailed Description

The client interface to the time zone server.

This class performs two basic functions:

1. Converts between UTC time and local time. 2. Sets the current local time zone.

NOTE: The presence of a time zone server will alter the behaviour of the time zone related function calls User::SetUTCOffset() and User::SetUTCTimeAndOffset(). The time zone server is shutdown when the last session (RTz) is closed. Therefore, to maintain consistent time related behaviour, licensees may want to keep a system level time zone server session open at all times.

Exceptional cases occur when a user requests conversion for a non-existent local time or a double local time.

Non-existent local times occur when the local time changes from winter to summer for DST.

For example, 01:59 local time is non-existent on the day of a change to BST in Europe/London since the time changes directly from 12:59:59 to 2:00.

A double local time occurs when the local time changes from summer to winter.

For example, if the time changes at 02:00 AM BST to 01:00 AM GMT then local times between 01:00 and 01:59 occur twice.

The conversion applies the DST offset if the local time value is double and applies the standard UTC offset if the local time does not exists.

This decision makes the conversion process asymmetrical around the discontinuity in the local time when there is a DST change.

An example conversion from a double local time to UTC and from UTC to a double local time is:

01:59 AM BST => 00:59 AM UTC 01:59 AM UTC => 01:59 AM GMT

An example conversion from a non-existent local time to UTC and from UTC to local time is:

01:59 AM GMT => 01:59 AM UTC 01:59 AM UTC => 02:59 AM BST

Since: 9.1

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.

Parameters
aTimeZone	Time zone names information to store in the given frequently used time zone.
aCity	City associated with the time zone names to store in the given frequently used time zone.
aFrequentlyUsedZone	Which frequently used time zone to overwrite in the database.

SetAutoUpdateBehaviorL ( TTzAutoDSTUpdateModes )

IMPORT_C void

SetAutoUpdateBehaviorL

(

TTzAutoDSTUpdateModes

aUpdateEnabled

)

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

Parameters
aUpdateEnabled	If set to RTz::ETZAutoDSTUpdateOn then the UTC Offset is automatically updated for changes to Daylight Savings Time. If set to RTz::ETZAutoDSTUpdateOff then auto-update is disabled. The RTz::ETZAutoDSTNotificationOnly - Means that the client app needs to confirm that the time should be updated whenever a DST event occurs.

SetHomeTime ( const TTime & )

IMPORT_C TInt

SetHomeTime

(

const TTime &

aLocalTime

)

const

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))

Parameters
aLocalTime	The time to set in wall-clock time.

Return Value: An error code. KErrNone is expected unless there is an error in converting the given local time to UTC.

Capability
WriteDeviceData

SetTimeZoneL ( CTzId & )

IMPORT_C void

SetTimeZoneL

(

CTzId &

aZone

)

const

This should not be used externally.

Sets the current system time zone information to that corresponding to the supplied time zone ID.

Parameters
aZone	The time zone ID.

Capability
WRITE_DEVICE_DATA

SetUnknownZoneTimeL ( const TTime &, const TInt )

IMPORT_C void	SetUnknownZoneTimeL	(	const TTime &	aUTCTime,
			const TInt	aUTCOffset
		)

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.

Parameters
aUTCTime	Universal Time to set the device time to.
aUTCOffset	Offset (in minutes) in use in the time zone.

SetUnknownZoneTimeL ( const TTime &, const TInt, TBool )

IMPORT_C void	SetUnknownZoneTimeL	(	const TTime &	aUTCTime,
			const TInt	aUTCOffset,
			TBool	aPersistInCenRep
		)

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

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.

Parameters
aUTCTime	Universal Time to set the device time to.
aUTCOffset	Offset (in minutes) in use in the time zone.
aPersistInCenRep	If ETrue the unknown time zone is persisted across reboots else it is not.
