时间换算 一天24个小时 比如说2016-12-31 23:50：50 这个加上2小时要变分钟 要变小时 变天 变月份 变年 还有就是减的时候 2016-1-1 0：00 减去2小时 也要都变 我想问的是 我下面中的代码逻辑 是不是写错了 错在那里 求指导
对了 北京时间是utc +8 那 utc+3.5 是小时+3 分钟 +5 还是+30 还是什么
在线急等 谢谢 之前也问过 有哥 给我写了另一个简单方法 没看懂 没弄明白 所在又问了一遍
看我原来的那个帖子，获取UTC时间字符串，每次计算都要 new 一个新的UTC事件，通过api更新时间对象后在调用方法设置时间，而不是直接操作
d.getUTCHours() + 3
这样来操作，所以会显示>24或者<0的情况出现
下面只改了部分，其他没改的按照写的示例修改
function updateDate() {
var d = new Date();
var a = d.getUTCHours();
//UTC时间字符串
var sUTC = d.getUTCFullYear() + '/' + (d.getUTCMonth() + 1) + '/' + d.getUTCDate() + ' ' + d.getUTCHours() + ':' + d.getUTCMinutes() + ':' + d.getUTCSeconds();
//世界标准时间
$("#time").val(d.getUTCFullYear() + "年" + (d.getUTCMonth() + 1) + "月" + d.getUTCDate() + "日 " + d.getUTCHours() + ":" + d.getUTCMinutes() + ":" + d.getUTCSeconds());
//当地时间
$("#time1").val(d.getFullYear() + "年" + (d.getMonth() + 1) + "月" + d.getDate() + "日 " + d.getHours() + ":" + d.getMinutes() + ":" + d.getSeconds());
//惠灵顿时间
d = new Date(sUTC)//新UTC时间对象
d.setHours(d.getHours() + 12);
//因为是经过UTC计算得到的事件，就不需要在调用getUTCXXXXX这种方法了，直接调用getXXXX
$("#time2").val(d.getFullYear() + "年" + (d.getMonth() + 1) + "月" + d.getUTCDate() + "日 " + d.getHours() + ":" + d.getMinutes() + ":" +d.getSeconds());
//悉尼时间
d = new Date(sUTC)//新UTC时间对象
d.setHours(d.getHours() + 10);
$("#time3").val(d.getFullYear() + "年" + (d.getMonth() + 1) + "月" + d.getUTCDate() + "日 " + d.getHours() + ":" + d.getMinutes() + ":" + d.getSeconds());
///////////////////////////下面的按照上面的改，分钟的话用 d.setMinutes(d.getMinutes()+要增加的分钟数)，看新德里的那个句
