PHP ISO 86601 format date?-CodePudding

I'm trying to create a date in this exact format:

2022-05-19T02:00:00.000 02:00

And I'm doing this:

$todayDate = new DateTime('19-05-2022', new DateTimeZone('Europe/Madrid'));
$todayDate->format(DateTime::ATOM),

But the output looks like this:

2022-05-19T00:00:00 02:00

There's a subtle difference:

2022-05-19T02:00:00.000 02:00  <-- wanted
2022-05-19T00:00:00 02:00 <-- the one I got

Any way I can get the one I need? What format would that be?

As indicated by the documentation on DateTime constants, you're looking for DateTimeInterface::RFC3339_EXTENDED (example: 2005-08-15T15:52:01.000 00:00) rather than DateTimeInterface::ATOM, also known as DateTimeInterface::RFC3339 (exemple: 2005-08-15T15:52:01 00:00).

I assume the questioner wants to transfer a pure date ( with the time 00:00 ) to another time zone. He wants to get hours '02'.

If a very specific fixed format is needed, I don't recommend using predefined constants that may no longer exist or may be changed in a future PHP version.

$strDate = date_create('19-05-2022', new DateTimeZone('UTC'))
  ->setTimeZone(new DateTimeZone('Europe/Madrid'))
  ->format("Y-m-d\TH:i:s.vP")
;

echo $strDate;
//2022-05-19T02:00:00.000 02:00
