Unity是由Unity Technologies开发的一个让玩家轻松创建诸如三维视频游戏、建筑可视化、实时三维动画等类型互动内容的多平台的综合型游戏开发工具，是一个全面整合的专业游戏引擎。Unity类似于Director,Blender game engine, Virtools 或 Torque Game Builder等利用交互的图型化开发环境为首要方式的软件其编辑器运行在Windows 和Mac OS X下，可发布游戏至Windows、Mac、Wii、iPhone、Windows phone 8和Android平台。也可以利用Unity web player插件发布网页游戏，支持Mac和Windows的网页浏览。它的网页播放器也被Mac widgets所支持。
下面通过一段代码给大家介绍unity3d获取系统时间。
具体代码如下所示：
var gSkin:GUISkin;
var str="";
var Months:String[]=["一月","二月","三月","四月","五月","六月","七月","八月","九月","十月","十一月","十二月"];
var Days:String[]= ["１","２","３","４","５","６","７","８","９","10","11","12","13","14","15","16","17","18","19","20",
"21","22","23","24","25","26","27","28","29","30","31"];
var dNow:System.DateTime;
var i=0;
function OnGUI()
{if(gSkin)GUI.skin=gSkin;
GUILayout.Box("本地日期时间："+System.DateTime.Now);//本地时间，12小时制的
GUILayout.Box("军事日期时间："+System.DateTime.Now.ToString("yyyyMMddHHmmss"));
GUILayout.Box("UTC日期时间："+System.DateTime.UtcNow);//UTC时间
GUILayout.SelectionGrid(System.DateTime.Now.Month-1,Months,3);
GUILayout.SelectionGrid(System.DateTime.Now.Day-1,Days,10);
GUILayout.Box(str+dNow.Now.Year+"年"+dNow.Now.Month+"月"+dNow.Now.Day+" 日"+" "+dNow.Now.Hour+"时"+dNow.Now.Minute+"分"+dNow.Now.Second+"秒");
}
以上代码就是关于Unity3d获取系统时间的全部内容，代码附有注释，哪里写的不好的地方欢迎各位大侠提出宝贵意见。谢谢。
