讨论一个时间转换的难题,大家讨论

[linus_liu2000]

我有一个字符串,里面包含着UTC标准时间:"2009.08.20 0200UTC" 0200表示2点正.
求一个转换函数,把这个字符串变成 表示新西兰当地时间的字符串.

#         }   
#   
#   
#   
# }   

这是转成当地时间的，换成新西兰的就可以了

请问楼上,你代码中带那么多#有何作用?

[justinavril]

UTC时间与GMT时间是一样的 与英国伦敦的本地时间一样

中国在GMT+8区，也就是中国早GMT和UTC标准时间8小时，而新西兰在GMT+12区（这个不太确定），也就是早UTC标准时间12小时

或者利用Calendar类自动实现 中午吃完饭写写 来验证下上面的话 对不对吧

没太看懂,应该在哪换成新西兰的时间?
