如果flash中，我们想实现一张图片随着计算机时间的变换，图片也发生变化，形成早晨，晚上等效果。（如果多个图片，也能用这个方法实现，下面，我们看一下案例）：
相对应的脚本：
function times()
{
hh = new Date();
xiaoshi = hh.getHours();
mm = new Date();
fengzhong = mm.getMinutes();
nowtime = xiaoshi * 60 + fengzhong;
if (nowtime >= 0 && nowtime <= 300 || nowtime > 1200 && nowtime < 1440)
{
skycolor = [5, 18, 7, -14, 29, -10, 100, 0];
} // end if
if (nowtime > 300 && nowtime <= 330)
{
skycolor = [5 + (nowtime - 300) * 1.500000, 18 - (nowtime - 300) * 2.930000, 7 + (nowtime - 300) * 1.200000, -14 - (nowtime - 300) * 1.230000, 29 + (nowtime - 300), -10 - (nowtime - 300) * 1.330000, 100, 0];
