PHP - Sort By Date/time

Hi,
I've done a search and cant find anything related to my problem.
I have a newsfeed on my site and i want it to display with the latest news at the top.
I have this code:
Code: [Select]
$get_news = "SELECT title, text, DATE_FORMAT(datetime, '%e %b %Y at %T') AS datetime FROM newsfeed ORDER BY datetime DESC";
This works fine on one of my sites but on another i've just hit a problem. It seems to sort only by the day, not the rest of the date.
I made a news post today with date and time of "27 Mar 2011 at 12:54:02" but a post from "28 Jan 2011 at 19:59:52" is above it.

Any ideas why this is happening?

Thanks,
Alex

Hey guys,
How would I go about subtracting Today from a previous day to find the difference?

For example, I want to subtract TODAY from a previous date in my database, to determine if the difference is greater than 1 day.

Any ideas? I tried doing the subraction in TIMESTAMPS, but when I convert the date back to Y-m-d H:i:s, I got some weird year and time.
 

ok so my problem is i need my data to be sorted by date which comes first.. how do i do it..can someone help me..if possible elaborate some codes? thxx..

so this is my program

Code: [Select]

<?
$b=$_GET['b'];
$m=$_GET['m'];
$y=$_GET['y'];

if  ($b <> '' && $m <> '' && $y <> '') {

$branch=$b;
$leavemonth=$m;
$leaveyear=$y;
}
else
{
$branch=$_POST['branch'];
$leavemonth=$_POST['leavemonth'];
$leaveyear=$_POST['leaveyear'];
}

mysql_select_db($database_name, $connection)

Hello everyone,
This is my first post and i have a question that im sure is easy to answer, im a beginner in PHP and i know how to submit a form and so on into mysql, now my question is, for everything i submit i would like for it to organize by date just like www.WorldStarHipHop.com, but not sure on how to do it. Any Clue? how do i get each indivual form i submit to automatically appear with the correct date untop? and how do i make the date appear untop of each section? Thanks for your time!

Hey guys,

I have got some events, and got it sorted by date, although at the moment the oldest date is showing first, and I would like to turn that around(new first old last), any simple suggestions?

Also another little question how would I turn a date row (for example 2009/5/31) into Tuesday - May 2009 or something similar, anyone can point me into the right direction?
