Class CVersitDaylight

class CVersitDaylight : public CBase;

Description

Universal time offset information, including the daylight savings offset.

This class deals with the daylight saving offset: a one hour offset that occurs in many countries during part of the year. This offset needs to be taken into account when converting Versit times (TVersitDateTimes) between universal and machine-local times.

This class stores information about the offset, including its length in seconds, when it takes effect and the standard time designations.

Note that the universal offset (iOffset) is the sum of the daylight saving offset and any time zone offset, as it is the absolute offset from GMT.

An instance of this class is owned by the CParserPropertyValueDaylight class.

Members

Defined in CVersitDaylight:
NewL(), iDaylightDesignation, iEndTime, iOffset, iSavings, iStandardDesignation, iStartTime, iStartTimeSortKey, ~CVersitDaylight()

Inherited from CBase:
Delete(), Extension_(), operator new()

static IMPORT_C CVersitDaylight *NewL(TBool aSavings, TTimeIntervalSeconds aOffset, TVersitDateTime *aStartTime, TVersitDateTime *aEndTime, const TDesC &aStandardDesignation, const TDesC &aDaylightDesignation);

Description

Allocates and constructs a new universal time offset object.

Ownership of aStartTime and aEndTime is taken at end of this function.

Parameters

TBool aSavings The daylight savings flag, i.e. ETrue if daylight saving is currently observed in the locale; EFalse if not. TTimeIntervalSeconds aOffset The universal time offset (in seconds). TVersitDateTime *aStartTime The date/time at which the period for daylight saving begins. TVersitDateTime *aEndTime The date/time at which the period for daylight saving ends. const TDesC &aStandardDesignation The standard time designation, e.g. GMT, EST. const TDesC &aDaylightDesignation The daylight saving time designation, e.g. BST, EDT.

Return value

CVersitDaylight * The new universal time offset object.

IMPORT_C ~CVersitDaylight();

Description

The destructor frees all resources owned by the object, prior to its destruction.

TInt64 iStartTimeSortKey;

Description

A sort key than can be used when sorting an array of properties by start date/time.

TBool iSavings;

Description

The daylight savings flag: this is ETrue if daylight saving is in effect in the locale and EFalse if not.

TTimeIntervalSeconds iOffset;

Description

The absolute offset from GMT, which is the sum of the time zone and daylight saving offsets (in seconds).

TVersitDateTime * iStartTime;

Description

The date/time at which the period for daylight saving begins.

TVersitDateTime * iEndTime;

Description

The date/time at which the period for daylight saving ends.

HBufC * iStandardDesignation;

Description

The standard time designation, e.g. GMT, EST.

HBufC * iDaylightDesignation;

Description

The daylight saving time designation, e.g. BST, EDT.
