在母版页上使用此脚本
JavaScript计时器
Use this script on master page
Javascript Timer
使用javascript，您可以获取登录的datetime.将其存储在变量中.调用Java脚本方法一段时间..say1min，
Using javascript, you can get the logged in datetime.Store it in variable.Call a java script method for some interval..say 1min ,
log time = nowdate_time - logged in datetime.

Like:
<body onload="updateClock(); setInterval(''updateClock()'', 1000 );">
function updateClock ()
{
var Loggeddatetime = new Date ();
var LoggedHours = Loggeddatetime.getHours ();
var LoggedMinutes = Loggeddatetime.getMinutes ();
var LoggedSeconds = Loggeddatetime.getSeconds ();
// Pad the minutes and seconds with leading zeros, if required
LoggedMinutes = ( LoggedMinutes < 10 ? "0" : "" ) + LoggedMinutes;
LoggedSeconds = ( LoggedSeconds < 10 ? "0" : "" ) + LoggedSeconds;
// Choose either "AM" or "PM" as appropriate
var timeOfDay = ( LoggedHours < 12 ) ? "AM" : "PM";
// Convert the hours component to 12-hour format if needed
LoggedHours = ( LoggedHours > 12 ) ? LoggedHours - 12 : LoggedHours;
// Convert an hours component of "0" to "12"
LoggedHours = ( LoggedHours == 0 ) ? 12 : LoggedHours;
// Compose the string for display by calculating the difference
//var currentTimeString
// Update the time display
document.getElementById("<%=lblDateTime1.ClientID %>").innerHTML = currentTimeString;
}
