(new Date(1291656749000)).toUTCString()

I would go with (new Date(integer)).toUTCString(),
我会用(new Date(integer)).toUTCString(),
but if you have to have the 'pm', you can format it yourself:
但是如果你必须有'pm',你可以自己格式化:
function utcformat(d){
d= new Date(d);
var tail= 'GMT', D= [d.getUTCFullYear(), d.getUTCMonth()+1, d.getUTCDate()],
T= [d.getUTCHours(), d.getUTCMinutes(), d.getUTCSeconds()];
if(+T[0]> 12){
T[0]-= 12;
tail= ' pm '+tail;
}
else tail= ' am '+tail;
var i= 3;
while(i){
--i;
if(D[i]<10) D[i]= '0'+D[i];
if(T[i]<10) T[i]= '0'+T[i];
}
return D.join('/')+' '+T.join(':')+ tail;
}
alert(utcformat(1291656749000))
警报(utcformat(1291656749000))
/* returned value: (String) 2010/12/06 05:32:29 pm GMT */
/* 返回值:(字符串)2010/12/06 05:32:29 pm GMT */
