Re: The GetTimeZoneInfo() function
How interesting! Late this afternoon I "played" around your initial js code
for tz,
I attempted to send this js tz value to a form hidden field, then, have another
js function to auto submit the form, then, have cf get its value, within the
same template, tried it for about 15/20 minutes to no avail. I switched to sql
to solve the problem. Thanks though.

RE: The GetTimeZoneInfo() function
To get the time information from Javascript into Cf, you would need to run a
javascript that will send the time information as either a url var or a form
var to a page on the server that will save it as a variable.
The 'next' page will have that information available to it, but the page you
just ran will not.
Eg.
Run index.cfm page.
=contains
var thistime = new Date();
var req;
req = false;
if(window.XMLHttpRequest && !(window.ActiveXObject)) {
try {
req = new XMLHttpRequest();
} catch(e) {
req = false;
}
} else if(window.ActiveXObject) {
try {
req = new ActiveXObject("Msxml2.XMLHTTP");
} catch(e) {
try {
req = new ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {
req = false;
}
}
}
if(req) {
req.onreadystatechange = processReqChange;
req.open("POST","<a rel="nofollow" href="http://[servername]/[pagename.cfm]"">http://[servername]/[pagename.cfm]"</a>;, true);
req.setRequestHeader('Content-Type','application/x-www-form-urlencoded');
req.send("time=" + thistime);
}
}
Or something like that.

I'm interested. William Seiter's js code works fine, but don't know how to
convert js var into CF var (key to this thing). thanks. Don

That's neat, it also works with IE7. Now, I'm a bit scare of script kitty, not
this one or the like.

RE: The GetTimeZoneInfo() function
That is correct, the querant only asked about timezone, however, if we limit
our responses to just 'what the querant asked about' there may be a world of
solutions that the querant had not even anticipated, hence the further
reference I had made to find out what the need was for.
As for timezone...
When I do this line of code:
var currentTime = new Date();document.getElementById('writedate').innerHTML
= currentTime;
I get this result in FF:
Tue Feb 19 2008 20:11:51 GMT-0800 (Pacific Standard Time)
That appears to contain a timezone reference both by name and by GMT count.

Thank you both about the JS option, I looked into that as well... but I'll stick to my sql solution for it (it's working fine and seem efficient).

RE: The GetTimeZoneInfo() function
I believe you can use JS to pull the local computer's time and then use AJAX to send that information back to the server, however if this is for a security system or an application's vital information, a user can just change their local date/time to overcome the system. If you tell us what the end use will be for the information we may be able to guide you with more useable information. William -- William E. Seiter Have you ever read a book that changed your life?
