Javascript时间问题

我有这个代码：

<script type="text/javascript">
var currenttime = '<? print date("F d, Y H:i:s", time()) ?>'
var montharray=new Array("January","February","March","April","May","June","July","August","September","October","November","December")
var serverdate=new Date(currenttime)
function padlength(what){
var output=(what.toString().length==1)? "0"+what : what
return output
}
function displaytime(){
serverdate.setSeconds(serverdate.getSeconds()+1)
var datestring=montharray[serverdate.getMonth()]+" "+padlength(serverdate.getDate())+", "+serverdate.getFullYear()
var timestring=padlength(serverdate.getHours()+1)+":"+padlength(serverdate.getMinutes())+":"+padlength(serverdate.getSeconds())
var minleft=60-serverdate.getMinutes()
var secleft=60-serverdate.getSeconds()
var houleft=24-serverdate.getHours()+1
var newenergyin=padlength(minleft)+":"+padlength(secleft)
var gainin=padlength(houleft)+":"+padlength(minleft)+":"+padlength(secleft)
document.getElementById("servertime").innerHTML=timestring
document.getElementById("moreenergy").innerHTML=newenergyin
document.getElementById("inter").innerHTML=gainin
}
window.onload=function(){
setInterval("displaytime()", 1000)
}
</script>

我的有问题

document.getElementById("inter").innerHTML=gainin

代码的一部分。如果我做

<span id='inter'></span>

它不想工作，但我用做的前一个

document.getElementById("moreenergy").innerHTML=newenergyin

工作非常好。

我做错了什么？！我只想显示午夜倒计时，倒计时到下一个小时效果良好：S

HTML:

<td><center><b>- Currency -</b></center>Credits: <a href='main.php?id=depcre'>0</a>    
<br>Platinum: <font color='orange'>46</font><br>Waste Magic: <font color='orange'>48</font>    
<br>Copper: <font color='orange'>49</font><br>Silver: <font color='orange'>48</font>    
<br>Gold: <font color='orange'>47</font><br><br>Bank: <a href='main.php?id=witcre'>841</a>    
<Small> (<font color='orange'>0.25%</font> IGDA)</small><br>Interest Gain In: <font     color='orange'><span id='inter'></span></font></td>

好的，整个HTML:

<script type="text/javascript">
var currenttime = '<? print date("F d, Y H:i:s", time()) ?>'
var montharray=new Array("January","February","March","April","May","June","July","August","September","October","November","December")
var serverdate=new Date(currenttime)
function padlength(what){
var output=(what.toString().length==1)? "0"+what : what
return output
}
function displaytime(){
serverdate.setSeconds(serverdate.getSeconds()+1)
var datestring=montharray[serverdate.getMonth()]+" "+padlength(serverdate.getDate())+", "+serverdate.getFullYear()
var timestring=padlength(serverdate.getHours()+1)+":"+padlength(serverdate.getMinutes())+":"+padlength(serverdate.getSeconds())
var minleft=60-serverdate.getMinutes()
var secleft=60-serverdate.getSeconds()
var houleft=24-serverdate.getHours()+1
var newenergyin=padlength(minleft)+":"+padlength(secleft)
var gainin=padlength(houleft)+":"+padlength(minleft)+":"+padlength(secleft)
document.getElementById("servertime").innerHTML=timestring
document.getElementById("moreenergy").innerHTML=newenergyin
document.getElementById("inter").innerHTML=gainin
}
window.onload=function(){
setInterval("displaytime()", 1000)
}
