Question

I have looked at this question but time format is different

I have following date format Tue, 11 Sep 2012 17:38:09 GMT
in $pubDate variable

I would like to compare $pubDate with current Date and Time to see if Tue, 11 Sep 2012 17:38:09 GMT is in last 10 mins or not

EDIT:

I have tried

//get current time
                strtotime($pubDate);
                time() - strtotime($pubDate);
                if((time()-(60*10)) < strtotime($pubDate)){
                    //if true increase badge by one
                    $badge = $badge + 1;
                }

it gives the warning:
It is not safe to rely on the system’s timezone settings. You are required to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected ‘America/New_York’ for ‘EDT/-4.0/DST’ instead in /Users/xxxxx/Desktop/xxxx/xxxx/xxxx.php on line 26

EDIT:

I have added date_default_timezone_set('America/New_York'); line to my php and now

$inDate  = DateTime::createFromFormat( $format, $pubDate);
    $postDate = new DateTime();

    $diff = $inDate->diff( $postDate);

    // If the total number of days is > 0, or the number of hours > 0, or the number of minutes > 10, then its an invalid timestamp.
    if( $diff->format( '%a') > 0 || $diff->format( '%h') > 0 || $diff->format( '%i') > 10) {
     die( 'The timestamps differ by more than 10 minutes');
    }

works without warning, Thanks everyone

Use DateTime to do the comparison:

$format = 'D, d M Y H:i:s O';
$tz = new DateTimeZone( 'America/New_York');

// Create two date objects from the time strings
$pubDate  = DateTime::createFromFormat( $format, 'Tue, 11 Sep 2012 17:38:09 GMT', $tz);
$postDate = DateTime::createFromFormat( $format, 'Tue, 11 Sep 2012 17:38:09 GMT', $tz);

// Compute the difference between the two timestamps
$diff = $pubDate->diff( $postDate);

// If the total number of days is > 0, or the number of hours > 0, or the number of minutes > 10, then its an invalid timestamp.
if( $diff->format( '%a') > 0 || $diff->format( '%h') > 0 || $diff->format( '%i') > 10) {
    die( 'The timestamps differ by more than 10 minutes');
}

You can play around with it and see it working in this demo.
