Calculate time difference in hours

Copy linkTweet thisAlerts:
May 30.2004

Hi there to you all!

I’m new to java, used to programming in SQL, VB, HTML and Flash only.

However, I have a problem that could be best solved with Java. Can anyone help me please?

I need to calculate a time difference between the exact current date and 05/28/2004 10:00:00 AM in hours.

After obtaining these hours (eg 52 at the very moment), I need to divide them by 100 and add them to 35. The current value would be 35,52 at the moment.

Then the number should be output in a simple textbox.

I found some birthday calculators, but I seem to not quite get the knack.

This is for a timer on a homepage … of course I would thank the person who could provide me with the source code for this!

I hope someone can help me!

Greetings

Rhadan, RJ

Something like this:[code=php]<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Untitled</title>
<script language="JavaScript" type="text/javascript">
<!--
function getDiff(){
var oldDate=Date.parse(new Date(2004,4,28,10,0,0));
var newDate=Date.parse(new Date());
var diff=newDate-oldDate;
diff=diff/86400000*24;
diff=diff/100+35;
diff=diff.toFixed(2);
document.forms[0].timeDiff.value=diff;
}
//-->
</script>
</head>
<body onload="getDiff()">
<form>
<input name="timeDiff">
</form>
</body>
</html>[/code]Cheers - Pit

@rhadanauthorMay 30.2004 — Thank you, seems to work very well!

I take it if it exceeds 35,99 it will switch to 36?

Any special credits I can give you or just your name??

Thanks again!

You're welcome!I take it if it exceeds 35,99 it will switch to 36?[/QUOTE]Of course, but only if the document is reloaded; it will show what you want anytime a user enters the page with the code in it.

No need to put some credit, I am glad to help and that's enough. I have observed, that you repeatedly use a comma as a decimal separator (which in Germany - where I live - is the case as well). Do you want the "." to be replaced with a ","?

@PittimannMay 30.2004 — Hi!

Ist aber kinderleicht: diese beiden Zeilen

diff=diff.toString();

diff=diff.replace('.',',');

gehören dazu vor diese:

document.forms[0].timeDiff.value=diff;

Nochmals: keine Ursache!

Ahoi - Pit
