| class CParserTimePropertyValue : public CParserPropertyValue |
Abstract base class for all of the date/time property value classes.
Provides date/time conversion functions between machine-local and universal time.
The date/time property value classes are CParserPropertyValueAlarm, CParserPropertyValueDate, CParserPropertyValueDateTime, CParserPropertyValueMultiDateTime, CParserPropertyValueDaylight and CParserPropertyValueRecurrence.

This is implemented, where applicable, to convert date/time values into universal time.
The date/time is checked against the daylight saving information provided in aDaylight. If it falls inside the daylight saving period then the daylight saving offset is subtracted from the time to convert it to universal time. Otherwise aIncrement is added to the date/time of the alarm to convert it to universal time.
Note that the daylight savings offset will adjust the time both for the daylight saving and for the time zone.
The function has no effect if it date/times are already stored in universal time.
If aDaylight is a NULL pointer then aIncrement is used.
since 9.1
| const TTimeIntervalSeconds & aIncrement | A time interval in seconds which represents the time zone's offset from universal time. |
| const CVersitDaylight * aDaylight | Pointer to the specification for daylight saving. If the alarm's time value is within the period for daylight saving, the value is modified by the daylight saving offset (which accounts for both the time zone and daylight saving rule). |
| IMPORT_C void | ConvertAllUTCDateTimesToMachineLocalL | ( | const TTimeIntervalSeconds & | aIncrement | ) | [pure virtual] |
Pure virtual function which is implemented, where applicable, to convert the date/time property value into machine-local time.
This process involves adjusting the date/time value by the offset in aIncrement.
The function has no effect if the value is already stored as machine-local time.
The universal date/times are assumed to have been corrected for any daylight saving rule in effect.
since 9.1
| const TTimeIntervalSeconds & aIncrement | A time interval which represents the number of seconds which is to be added to the date/time value. This should normally be the universal time offset for the machine's locale. |
