You could always try something like this...
你总是可以尝试这样的事情......
var d = new Date("December 31, 2010 03:55:00");
alert (d);
var hourString;
var amPm = "AM";
if ( d.getHours() > 11 ) {
amPm = "PM"
hourString = "0" + (d.getHours() - 12);
} else {
amPm = "AM"
hourInt = "0" + d.getHours();
}
var formattedDate = "" + d.getDate() + "/" + (d.getMonth()+1) + "/" + d.getFullYear() + " " + hourInt + ":" + d.getMinutes() + " " + amPm;
alert (formattedDate);

You can get the time like this.
你可以得到这样的时间。
var dates=new Date("31/12/2010 03:55 AM");
var hour=dates.getHours());
var minutes=dates.getMinutes();
var seconds=dates.getSeconds();
Converts the time portion of a Date object to a string
将 Date 对象的时间部分转换为字符串
var timeString=dates.toTimeString());
Comparing two dates
比较两个日期
var date1=new Date("31/12/2010 03:55 AM");
var date2=new Date("31/1/2011 03:55 AM");
if(date1.getTime()>date2.getTime()){
alert(" date1 is greater ");
}else{
alert(" date1 is less");
}

Use the following functions to extract time from Javascript datetime object,
使用以下函数从 Javascript datetime 对象中提取时间，
Qusetion 1(extracting time)
问题1（提取时间）
Var Date=new Date();
var HH=Date.getHours();//yeilds hours
var mm=Date.getMinutes();//yields minutes
var ss=Date.getSeconds();//yields seconds
After this construct a string with the above results,
在此构造一个具有上述结果的字符串后，
var Time=HH+':'+mm+':'+ss;
Question 2(comparing dates)
问题 2（比较日期）
Java Script Section,
Java脚本部分，
function CompareStartAndEndDate(sender,args) {
var txtFromDate = document.getElementById('<%=txtFromDate.ClientID %>');
var txtToDate = document.getElementById('<%=txtToDate.ClientID %>');
var a = txtFromExpiryDate.value.split('/'); //split the date string received using /(if it is in dd/MM/yyyy ).
var b = txtToExpiryDate.value.split('/'); //split the date string received using /(if it is in dd/MM/yyyy ).
var startDate = new Date(a[2], a[1] - 1, a[0]); //create a javaScript datetime object using the above date parts.
var endDate = new Date(b[2], b[1] - 1, b[0]); //create a javaScript datetime object using the above date parts.
var dateStatus = IsDateGreater(endDate, startDate); //call a different function to find difference and get the result as boolean an our requirement.
if (dateStatus) {
args.IsValid = false;
}
else {
args.IsValid = true;
}
}
function IsDateGreater(DateValue1, DateValue2) {
var date1 = DateValue1.getTime();
var date2 = DateValue2.getTime();
//date1-date2 yield date diff in milli seconds.
if (date1 < date2)
return true;
else
return false;
}
Aspx section,
Aspx部分，
Here the comparison is done using a asp.net CustomValidator,
这里的比较是使用 asp.net CustomValidator 完成的，
<asp:TextBox ID="txtFromDate" runat="server" CssClass="txt-input"></asp:TextBox>
<asp:TextBox ID="txtToDate" runat="server" CssClass="txt-input"></asp:TextBox>
<asp:CustomValidator ID="valCustmCheckDate" runat="server" ErrorMessage="To date should be later than From date" ForeColor="Red" ValidationGroup="Group1" ClientValidationFunction="CompareStartAndEndDate"></asp:CustomValidator> //This validator will call the client side javascript function (CompareStartAndEndDate) first on the click of the button below since the validation group of the customvalidator and the triggering button is same (Group1).
<asp:ImageButton ID="imgbtnAddLoginUser" runat="server" ImageUrl="~/Images/btn-add.gif" ValidationGroup="Group1" OnClick="imgbtnAddLoginUser_Click" />
Hope this helps...
希望这可以帮助...

Date time in "31/12/2010 03:55 AM"
“31/12/2010 03:55 AM”中的日期时间
var dat = new Date();
dat.format("dd/m/yy h:MM tt");
Compare 2 date times and need to find the greator of the 2 how can do that too.
比较 2 个日期时间，并且需要找到 2 的大者，这也如何做到。
Date dt1 = new Date();
Date dt2 = new Date();
if (dt1.getTime() > dt2.getTime())
{
alert("The first date is after the second date!");
}
