Re: Detect Tme Zone

Trevor L. said the following on 10/13/2005 12:39 AM:
These statements display the current (local) time with UTC offset

They show the time as set on the computer, not necessarily the current local time.

var d = new Date()
document.write (d)

For me, it displayed
Thu Oct 13 14:36:20 UTC+1000 2005
(Australia is 10 hours ahead of UTC)

You could extract the offset itself by searching the string for "UTC" and taking the next 5 characters. 

But it still may not be accurate, depending on the user's PC settings.

I display local time on my website by using the toLocale functions

function getTheDate()
{// returns local date
  var now = new Date()
  return now.toLocaleDateString()
}
//------------------------------

function getTheTime()
{// returns local time
  var now = new Date()
  return now.toLocaleTimeString()
}
//------------------------------
But

That doesn't show the time zone the user is in, it shows the time zone the users computer is set to. They may not always match. I live in one time zone if I travel 50 miles with my laptop, I am in a different time zone but I do not change my computer settings.
