Thus, if the hours is negative, the minutes and seconds must be negative or zero. or for some other reason, an exception is thrown. This offset is checked with another one whether they are equal. Obtains an instance of ZoneOffset using the ID. Being a value-based class, the use of identity-sensitive operations may lead to unpredictable results. This function is used to get the hash code for a particular ZoneID object. This class inherits the class ZoneId and implements the interface Comparable. The range of valid values will be retrieved for the field mentioned. In case no rule is available or the rules of JRE is different from that of time-zone, a call made to this function may lead to ZoneRulesException. All other ChronoField instances will throw an UnsupportedTemporalTypeException. However, new Java versions have come up with more useful and expressive classes such as ZoneId and ZoneOffset, for managing time-zones. However, if we have a Java 7 and before a project, we can still achieve the same result by relying on the java.util.TimeZone class with its getAvailableIDs() method: Why didn't Doc Brown send Marty to the future before sending him back to 1885?
