Server Date time at the client

[sreenath reddy]

Hi all

I need to show the user Server Date-time in my jsp and it should be running ins ysnc with the server ............This is because the client needs to be aware of the server time as he needs to enter date-time for doing some specific task .............

Is there anyway to do that ?? i have an idea to implement the time (but not date) .ie on loading of the page i will get the server time and through some a javascript function i will execute a function after every second and i will manually run that clock(i mean after every second i will increment the seconds and if it reaches 59 i will increment the minutes field..........)


so can any one help me in implementing this ??

This is what I would do:

<script type="text/javascript">
 
  //Users time
  var timeLocal = new Date();
  //Servers time
  var timeServer = new Date("<%= time date string from server %>");
 
  //Calculate the difference (returns milliseconds)
  millDiff = timeLocal - timeServer;
 
  //initalize the clock on loading of page
  window.onload=function(){
    //set the interval so clock ticks
    var timeClock=setInterval("TimeTick()",10);
  }
 
  //The ticking clock function
  function TimeTick(){
    //grab updated time
    timeLocal = new Date();
    //add time difference
    timeLocal.setMilliseconds(timeLocal.getMilliseconds() - millDiff);
    //display the value
    document.getElementById("spanTime").innerHTML =timeLocal;
  }
 
</script>
<span id="spanTime"></span>
