本文整理了Java中java.util.TimeZone.getRawOffset()方法的一些代码示例，展示了TimeZone.getRawOffset()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。TimeZone.getRawOffset()方法的具体详情如下：
包路径：java.util.TimeZone
类名称：TimeZone
方法名：getRawOffset

TimeZone.getRawOffset介绍

[英]Returns the amount of time in milliseconds to add to UTC to get standard time in this time zone. Because this value is not affected by daylight saving time, it is called raw offset.

If an underlying TimeZone implementation subclass supports historical GMT offset changes, the method returns the raw offset value of the current date. In Honolulu, for example, its raw offset changed from GMT-10:30 to GMT-10:00 in 1947, and this method always returns -36000000 milliseconds (i.e., -10 hours).
[中]返回要添加到UTC以获取此时区的标准时间的时间量（以毫秒为单位）。由于该值不受夏令时的影响，因此称为原始偏移。
如果基础TimeZone实现子类支持历史GMT偏移量更改，则该方法返回当前日期的原始偏移量值。例如，在火奴鲁鲁，其原始偏移量在1947年从GMT-10:30更改为GMT-10:00，该方法始终返回-36000000毫秒（即-10小时）。
