如何在PHP上获取DateTime格式：2016-01-29T09：29：29.5033083 + 03：00

Question

Who can say that over time, the date format is used here?

<Date>2016-01-29T09:29:29.5033083+03:00</Date>

I tried to do it on php$time = microtime();

list($usec, $sec) = explode(" ", $time);
$datetime = new DateTime();
$datetime->setTimestamp($time);
$usec = $usec * 1000000;
echo date('Y-m-d\TH:i:s.'.$usec.'P') . "<hr>";

Result:

 2016-05-19T12:52:04.415507+05:00

But the number of characters is not the same:

.5033083
.415507

How do I get this format to php?

<Date>2016-01-29T09:29:29.5033083+03:00</Date>

This may be help you

date_default_timezone_set('UTC');
echo date(DATE_ATOM, mktime(0, 0, 0, 7, 1, 2000));
//prints something like: 2000-07-01T00:00:00+00:00
