php fatal error with date

Question

This is my function:

public static function GetFormattedMicroTime($timestamp = false) {
    if(!$timestamp)
        $timestamp = microtime(true);
    return DateTime::createFromFormat('U.u',sprintf('%.f', $timestamp))->format('Y-m-d\TH:i:s.u');
}

This is how I call it (I'm calling it only from one point in my code):

$microtime = microtime(true);
$sinceLastLog = number_format($microtime - self::$lastLogTime,4);
self::$lastLogTime = $microtime;
return Utils::GetFormattedMicroTime($microtime) .'|'. $sinceLastLog .'| blah blah';

And I'm getting a lot of:

PHP message: PHP Fatal error: Call to a member function format() on a non-object

Can anybody help me troubleshoot?

EDIT:

I'm using php-fpm 5.4.28

i've changed my function a bit:

public static function GetFormattedMicroTime($timestamp = false) {
    if(!$timestamp)
        $timestamp = microtime(true);

    $d = DateTime::createFromFormat('U.u',sprintf('%.f', $timestamp));
    if ($d instanceof DateTime){
        return $d->format('Y-m-d\TH:i:s.u');
    } else {
        error_log("Erreur date ! timestamp = $timestamp erreur =".print_r(DateTime::getLastErrors(),true));
        return $timestamp;
    }
}

now i'm getting in nginx log:

PHP message: Erreur date ! timestamp = 1403539343,372 erreur = Array
(
    [warning_count] => 0
    [warnings] => Array
        (
        )
    [error_count] => 2
    [errors] => Array
        (
            [10] => Unexpected data found.
        )
)

You're probably trying to set a tab using format('Y-m-d\TH:i:s.u') use \t or \\t — Funk Forty Niner

DateTime::createFromFormat('U.u','1403538707.536290') doesn't work on version 5.3.0 and below. I don't know why this is however. — Jim

The locale affects the output of sprintf. Apparently, wherever you're getting this error from has a locale that uses a comma instead of a decimal point to separate whole and fractional digits. Essentially, it's trying to do this:

DateTime::createFromFormat('U.u','1403538707,536290')

createFromFormat just sees it as a decimal point character, not as the locale's decimal separator.

Try using number_format instead.

DateTime::createFromFormat('U.u', number_format($timestamp, 6, '.', ''));
