My server is in Atlanta, I am in Seattle.

What is the asp code for displaying the time difference? I am close but after midnight my time is off for a few hours until Seattle catches up ha ha!

Thanks everyone,
Jim S.

actually, you don't want to use datediff. that would show you the difference. use datadd:
DateAdd(interval, number, date)
see:

response.write dateadd("h", -3, now())

Here is client-side code to determine the difference between the browser time and GMT to get you started (if I recall correctly it's snipped from the MS documentation).  You can put the browser time in a hidden form field and when you submit the page you can compare to the server time using the server VBScript myTime=Now()

You can put the server time in your browser page and do all the comparison client-side if you wish.

function timezone() {

   var d, tz, s = "The current local time is ";
   d = new Date();
   tz = d.getTimezoneOffset();
   if (tz < 0)
      s += tz / 60 + " hours before GMT";
   else if (tz == 0)
      s += "GMT";
   else
      s += tz / 60 + " hours after GMT";
   return(s);
}

Thank you very much!

Exact answer... very nice answer... 1 line of code that's a bonus!!

Thank you to the other folks that gave answers also. msdixon got the nod because all I had to do was plug it in and it worked right off the bat.


Thanks,
