Examples of com.ibm.icu.util.TimeZoneRule

com.ibm.icu.util.TimeZoneRule
TimeZoneRule is an abstract class representing a rule for time zone. TimeZoneRule has a set of time zone attributes, such as zone name, raw offset (UTC offset for standard time) and daylight saving time offset. @see com.ibm.icu.util.TimeZoneTransition @see com.ibm.icu.util.RuleBasedTimeZone @stable ICU 3.8
