OK then... here it is:

<br />
function ConvertTZ(msgDate)<br />
{<br />
	date = new Date(msgDate);<br />
		date.setHours(date.getHours()-serverTZ+userTZ); //the convertion<br />
		<br />
		d = date.getDate();<br />
		m = (date.getMonth()+1);<br />
		h = date.getHours();<br />
		m = date.getMinutes();<br />
		<br />
		sDate = ((h<10)?"0"+h:h)+":"+((m<10)?"0"+m:m)+" "+((d<10)?"0"+d:d)+"-"+((m<10)?"0"+m:m)+"-"+date.getFullYear();	<br />
		document.write(sDate);<br />
	}

and this can be called like this

<td><br />
	<script>ConvertTZ("<%=Now%>")</script><br />
</td>

it can be tested here : http://xwega.com/codeproject/timezone.asp[^]

will Chris see this post? Big Grin | :-D

It would be cool to somehow determine time zone from IP addres or browser settings... or something.
Just a thought.

Close, but not quite. I am sure it is just typos but what is m supposed to be, month or minute? Also the month is displayed as three letters, not a two digit number. Also I agree with David, you should get the local timezone from the local machine, not from the user's profile. Just one less thing for the server to do.

[edit]
Also, not all time zones are full hours off of UTC. Newfoundland is -3.5.

Do not forget about daylight savings.

This is going to be more difficult then spending two minutes to slap together a small script. But keep working at it, it is avery good idea.

i think this is done also , because now i'm usin the get getTimezoneOffset() that return the value in minutes and calculating the correct time using minutes instead of hours

Any idea on how to calculate this?

Done the easy way!

I dont need to think of time zones or even daylight saving...

All i need is to get the date diff from server and client and apply that date diff to the date in question.

function ConvertTime(svrdate,anydate)<br />
	{<br />
		clientDate  = new Date();<br />
		serverDate	= new Date(svrdate);<br />
		date		= new Date(anydate);<br />
		<br />
		datediff	= (clientDate.valueOf()-serverDate.valueOf())/1000/60;  //minutes<br />
		date.setMinutes(date.getMinutes()+datediff);						//the convertion<br />
<br />
                h = date.getHours();<br />
		n = date.getMinutes();<br />
		sTime = h+":"+((n<10)?"0"+n:n)+" ";<br />
		sDate = new String(date.toUTCString());<br />
		//because string allways have the same format i place hardcoded values instead of making a search<br />
		sDate = sDate.substr(5,6); <br />
		sDate+=" '"+(String(date.getFullYear()).substr(2,2));<br />
		sTime+=sDate;<br />
		document.write(sTime);<br />
}<br />
<br />
<script>ConvertTime("<%=Now%>","03-25-2005 17:06")</script>

Looks good, but make sure you test it with a bunch of different dates (ie over new years, leap years, etc) to make sure all the bugs are out. Then maybe email it directly to Chris and see if he wants to go through the effort of integrating it.

That already exists, in fact Chris put that setting there just for the purpose you suggest. But since I see you're working on some script, I wanted to point out that the user's time zone is already available.

date.setMinutes(date.getMinutes()+datediff); //the convertion<br />
<br />
d = date.getDate();<br />
m = date.getMonth()+1;<br />
h = date.getHours();<br />
n = date.getMinutes();<br />
sTime = h+":"+((n<10)?"0"+n:n)+" ";<br />
sDate = new String(date.toUTCString());<br />
//because string allways have the same format i place hardcoded values instead of making a search<br />
sDate = sDate.substr(5,6); <br />
sDate+=" '"+(String(date.getFullYear()).substr(2,2));<br />

The timezone is already inplace in the profile but updating the timestamp everywhere in the site where a time is displayed hasn't been done because there are other items I feel a more important.

It's far, far easier simply to calculate an offset based on the reader's timezone and the server's timezone and then do

DateTime RelativeDate = AbsoluteDate.AddHours(Offset);
return RelativeDate.ToShortTimeString();

cheers,

i started to make a script using timezons ,but a very big problem came up (lightsaving).

Chris Maunder wrote:

yes it is , but you can do it all on the client side, less for the servers to do.
and in case you did not take a look at my previus posts on this thread Big Grin | :-D

here it is:

and one optimization can be made:
istead of sending the servertime to the function everytime , you can declare it inside the fuction, avoiding to much calls to "Now" on the server.

function ConvertTime(svrdate,anydate)<br />
{<br />
clientDate = new Date();<br />
serverDate = new Date(svrdate);<br />
date = new Date(anydate);<br />
<br />
datediff = (clientDate.valueOf()-serverDate.valueOf())/1000/60; //minutes<br />
date.setMinutes(date.getMinutes()+datediff); //the convertion<br />
<br />
h = date.getHours();<br />
n = date.getMinutes();<br />
sTime = h+":"+((n<10)?"0"+n:n)+" ";<br />
sDate = new String(date.toUTCString());<br />
//because string allways have the same format i place hardcoded values instead of making a search<br />
sDate = sDate.substr(5,6); <br />
sDate+=" '"+(String(date.getFullYear()).substr(2,2));<br />
sTime+=sDate;<br />
document.write(sTime);<br />
}<br />
<br />
<script>ConvertTime("<%=Now%>","03-25-2005 17:06")</script>

Why not displaying the server clock with javascript?
There could be multiple settings, e.g. a digital clock or analog clock.

Okay CodeProject - I want:

coffee cups with the cool little alien guy (CLAG(tm)... gal? hard to
tell Wink | ;)

I want some decent hats with the CLAG.

I want some t-shirts - quality t-shirts - with the CLAG and some
kind of catchy phrase. For example, I have a t-shirt from
Code Warrior - "Blood, Sweat, and Code."

Did I miss something on the web site?

Smile | :)

I think that was eggs (perhaps they forgot to mention they should be unfertilised)
