Detailed Description

SimpleTimeZone is a concrete subclass of TimeZone that represents a time zone for use with a Gregorian calendar.

This class does not handle historical changes.

When specifying daylight-savings-time begin and end dates, use a negative value for dayOfWeekInMonth to indicate that SimpleTimeZone should count from the end of the month backwards. For example, if Daylight Savings Time starts or ends at the last Sunday a month, use dayOfWeekInMonth = -1 along with dayOfWeek = UCAL_SUNDAY to specify the rule.

Member Enumeration Documentation

◆ TimeMode

enum icu::SimpleTimeZone::TimeMode

TimeMode is used, together with a millisecond offset after midnight, to specify a rule transition time.

Most rules transition at a local wall time, that is, according to the current time in effect, either standard, or DST. However, some rules transition at local standard time, and some at a specific UTC time. Although it might seem that all times could be converted to wall time, thus eliminating the need for this parameter, this is not the case.

Constructor & Destructor Documentation

◆ SimpleTimeZone() [1/5]

icu::SimpleTimeZone::SimpleTimeZone ( const SimpleTimeZone & source )

Copy constructor.

Parameters

source the object to be copied.

Stable:: ICU 2.0

◆ SimpleTimeZone() [2/5]

icu::SimpleTimeZone::SimpleTimeZone	(	int32_t	rawOffsetGMT,
		const UnicodeString &	ID
	)

Constructs a SimpleTimeZone with the given raw GMT offset and time zone ID, and which doesn't observe daylight savings time.

Parameters

rawOffsetGMT	The given base time zone offset to GMT.
ID	The timezone ID which is obtained from TimeZone.getAvailableIDs.

◆ getDynamicClassID()

virtual UClassID icu::SimpleTimeZone::getDynamicClassID ( void ) const

virtual

Override TimeZone Returns a unique class ID POLYMORPHICALLY.

Pure virtual override. This method is to implement a simple version of RTTI, since not all C++ compilers support genuine RTTI. Polymorphic operator==() and clone() methods call this method.

Returns: The class ID for this object. All objects of a given class have the same class ID. Objects of other classes have different class IDs.

Stable:: ICU 2.0

Implements icu::TimeZone.

◆ getNextTransition()

virtual UBool icu::SimpleTimeZone::getNextTransition	(	UDate	base,
		UBool	inclusive,
		TimeZoneTransition &	result
	)		const

virtual

Gets the first time zone transition after the base time.

Parameters

base	The base time.
inclusive	Whether the base time is inclusive or not.
result	Receives the first transition after the base time.

Returns: TRUE if the transition is found.

	)		const

virtual

Returns the TimeZone's adjusted GMT offset (i.e., the number of milliseconds to add to GMT to get local time in this time zone, taking daylight savings time into account) as of a particular reference date.

The reference date is used to determine whether daylight savings time is in effect and needs to be figured into the offset that is returned (in other words, what is the adjusted GMT offset in this time zone at this particular date and time?). For the time zones produced by createTimeZone(), the reference data is specified according to the Gregorian calendar, and the date and time fields are in GMT, NOT local time.

Parameters

era	The reference date's era
year	The reference date's year
month	The reference date's month (0-based; 0 is January)
day	The reference date's day-in-month (1-based)
dayOfWeek	The reference date's day-of-week (1-based; 1 is Sunday)

◆ getStaticClassID()

static UClassID icu::SimpleTimeZone::getStaticClassID ( void )

static

Return the class ID for this class.

This is useful only for comparing to a return value from getDynamicClassID(). For example:

virtual void icu::SimpleTimeZone::getTimeZoneRules	(	const InitialTimeZoneRule *&	initial,

		UErrorCode &	status
	)		const

virtual

Gets the InitialTimeZoneRule and the set of TimeZoneRule which represent time transitions for this time zone.

On successful return, the argument initial points to non-NULL InitialTimeZoneRule and the array trsrules is filled with 0 or multiple TimeZoneRule instances up to the size specified by trscount. The results are referencing the rule instance held by this time zone instance. Therefore, after this time zone is destructed, they are no longer available.

Parameters

initial	Receives the initial timezone rule
trsrules	Receives the timezone transition rules
trscount	On input, specify the size of the array 'transitions' receiving the timezone transition rules. On output, actual number of rules filled in the array will be set.
status	Receives error status code.

◆ inDaylightTime()

virtual UBool icu::SimpleTimeZone::inDaylightTime	(	UDate	date,
		UErrorCode &	status
	)		const

virtual

Returns true if the given date is within the period when daylight savings time is in effect; false otherwise.

If the TimeZone doesn't observe daylight savings time, this functions always returns false. This method is wasteful since it creates a new GregorianCalendar and deletes it each time it is called. This is a deprecated method and provided only for Java compatibility.

Parameters

date	The date to test.
status	An UErrorCode to receive the status.

Returns: true if the given date is in Daylight Savings Time; false otherwise.

inline

Sets the daylight savings starting rule.

For example, in the U.S., Daylight Savings Time starts at the second Sunday in March, at 2 AM in standard time. Therefore, you can set the start rule by calling: setStartRule(UCAL_MARCH, 2, UCAL_SUNDAY, 2*60*60*1000); The dayOfWeekInMonth and dayOfWeek parameters together specify how to calculate the exact starting date. Their exact meaning depend on their respective signs, allowing various types of rules to be constructed, as follows:

If both dayOfWeekInMonth and dayOfWeek are positive, they specify the day of week in the month (e.g., (2, WEDNESDAY) is the second Wednesday of the month).
If dayOfWeek is positive and dayOfWeekInMonth is negative, they specify the day of week in the month counting backward from the end of the month. (e.g., (-1, MONDAY) is the last Monday in the month)
If dayOfWeek is zero and dayOfWeekInMonth is positive, dayOfWeekInMonth specifies the day of the month, regardless of what day of the week it is. (e.g., (10, 0) is the tenth day of the month)
If dayOfWeek is zero and dayOfWeekInMonth is negative, dayOfWeekInMonth specifies the day of the month counting backward from the end of the month, regardless of what day of the week it is (e.g., (-2, 0) is the next-to-last day of the month).
If dayOfWeek is negative and dayOfWeekInMonth is positive, they specify the first specified day of the week on or after the specfied day of the month. (e.g., (15, -SUNDAY) is the first Sunday after the 15th of the month [or the 15th itself if the 15th is a Sunday].)
If dayOfWeek and DayOfWeekInMonth are both negative, they specify the last specified day of the week on or before the specified day of the month. (e.g., (-20, -TUESDAY) is the last Tuesday before the 20th of the month [or the 20th itself if the 20th is a Tuesday].)

Parameters

month	the daylight savings starting month. Month is 0-based. eg, 0 for January.
dayOfWeekInMonth	the daylight savings starting day-of-week-in-month. Please see the member description for an example.
dayOfWeek	the daylight savings starting day-of-week. Please see the member description for an example.
time	the daylight savings starting time. Please see the member description for an example.
