Re: The GetTimeZoneInfo() function
you *cannot* get the client's tz via js. Really? I just did. If anyone wants the java script to pull the timezone from FF and IE and put it in a form field let me know.

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
script
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,http://[servername]/[pagename.cfm];, true);
req.setRequestHeader('Content-Type','application/x-www-form-urlencoded');
req.send(time= + thistime);
}
}
/script
Or something like that.

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.
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.

Re: The GetTimeZoneInfo() function
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). The app is not pre-released yet but it's consumer-oriented, not exactly intended for int'l but more for N. America... 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.

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.
