Formatting the Client Time

Colonel Angus · February 4th, 2005, 02:40 PM

I am able to access the time on the client's machine clock by using the javascript getTime(); method. However, I'm going crazy trying to convert that value into a human-friendly format, like 1:37. Right now I get the milliseconds since Jan 1st 1970 (something like "1107542083053").

FYI, I am currently able to display the value from the client in a label through the Page_Load event. Getting the value is not an issue.

Thanks in advance for your comments.

I have a funtion that may help. I used this function to default drop down lists to the current time. You may be able to use it and just concantinate the time portions however you like. Hope this helps, let me know.

function formatDateTime()
{
   var currdate = new Date();
   var hourval = currdate.getHours();
   var minval = currdate.getMinutes();
   var AMPM = 0; //AM

   if (hourval >= 12)
   {
      AMPM = 1; //PM
   }

   if (hourval > 12)
   {
      hourval -=12;
   }

   document.frmCallBox.hour.selectedIndex = hourval - 1;
   document.frmCallBox.min.selectedIndex = minval;
   document.frmCallBox.ampm.selectedIndex = AMPM;
} //End formatDateTime()

Thanks J-

Actually, getting the current time this way was something I looked at previously, but I need to do a calculation with it. I'm adding 30 minutes (1,800,000 milliseconds) to it and then displaying that time to the user.

Sorry about not mentioning that earlier.

Not a problem.

Why not use the code and add 30 minutes to the minVal variable?

Something like:
var minval = currdate.getMinutes() + 30;

Jim-

Thanks for the insight. I took your idea and added some dressing around it.

Code:

function getExpTime(){
    var d = new Date();
    var curHour = d.getHours();
    var curMinute = d.getMinutes() + 30;
    if(curMinute >= 60){
        curHour += 1;
        curMinute -= 60;
    }
    if(curHour > 12){
        curHour = curHour - 12;
    }
    if(curMinute < 10){
        curMinute = "0" + curMinute;
    }
    var exp = curHour + ":" + curMinute;
    return exp;
}

Works like a charm. Thanks!
