/**@class java.time.ZoneOffset implements java.time.temporal.TemporalAccessor implements java.time.temporal.TemporalAdjuster implements java.lang.Comparable implements java.io.Serializable @extends java.time.ZoneId A time-zone offset from Greenwich/UTC, such as {@code +02:00}. <p> A time-zone offset is the amount of time that a time-zone differs from Greenwich/UTC. This is usually a fixed number of hours and minutes. <p> Different parts of the world have different time-zone offsets. The rules for how offsets vary by place and time of year are captured in the {@link java.time.ZoneId} class. <p> For example, Paris is one hour ahead of Greenwich/UTC in winter and two hours ahead in summer. The {@code ZoneId} instance for Paris will reference two {@code ZoneOffset} instances - a {@code +01:00} instance for winter, and a {@code +02:00} instance for summer. <p> In 2008, time-zone offsets around the world extended from -12:00 to +14:00. To prevent any problems with that range being extended, yet still provide validation, the range of offsets is restricted to -18:00 to 18:00 inclusive. <p> This class is designed for use with the ISO calendar system. The fields of hours, minutes and seconds make assumptions that are valid for the standard ISO definitions of those fields. This class may be used with other calendar systems providing the definition of the time fields matches those of the ISO calendar system. <p> Instances of {@code ZoneOffset} must be compared using {@link #equals}. Implementations may choose to cache certain common offsets, however applications must not rely on such caching. @implSpec This class is immutable and thread-safe. @since 1.8 */ var ZoneOffset = { /** The time-zone offset for UTC, with an ID of 'Z'. */ UTC : "null", /** Constant for the maximum supported offset. */ MIN : "null", /** Constant for the maximum supported offset. */ MAX : "null", /**Obtains an instance of {@code ZoneOffset} using the ID. <p> This method parses the string ID of a {@code ZoneOffset} to return an instance.
