类名称：ZoneRules
方法名：getOffset

ZoneRules.getOffset介绍

[英]Gets the offset applicable at the specified instant in these rules.

The mapping from an instant to an offset is simple, there is only one valid offset for each instant. This method returns that offset.
[中]获取适用于这些规则中指定时刻的偏移量。
从瞬间到偏移的映射很简单，每个瞬间只有一个有效偏移。此方法返回该偏移量。
