将System.out.println重定向到Log4J，同时保留类名称信息(Redirect System.out.println to Log4J, while keeping class name information)

 鉴于w3c模式文档中的以下句子： 
 
 
 
 假定“本地”或未定时的时间是由适当的法定机构规定的某个未指定地点的时区; 
 
 
 和 
 
 
 
 将时区添加到UTC dateTime时，结果是“在该时区内”的日期和时间。 
 
 
 这听起来不像是有一个明确的答案 。 我认为这通常是模棱两可的：两种版本都是基本有效的，使用哪个版本的问题取决于与系统连接的系统的配置/行为/期望。 
 
 即使有明确的答案，我也绝对不会依赖它，而是期望每个其他的Web服务和图书馆都有自己的方式来处理这个问题： 

Given the following sentences from the w3c schema documentation:
 
 
 
"Local" or untimezoned times are presumed to be the time in the timezone of some unspecified locality as prescribed by the appropriate legal authority;
 
 
and
 
 
 
When a timezone is added to a UTC dateTime, the result is the date and time "in that timezone".
 
 
it does not sound like there is a definitive answer to this. I would assume that it is the usual ambiguity: Both versions are principally valid, and the question of what version to use depends on the configuration/behavior/expectations of the system one is interfacing with.
 
And even if there where a definitive answer, I would definitely not rely on it, but rather expect that every other web service and library had its own way of dealing with this :/
