 New Comment:

I am marking this as Documentation Problems, as this behaviour is now long standing, and not only applicable for the 'u' character. The same behaviour occurs for other time related characters too.

We can break this behaviour again, but I am not really willing to do so.

Description:
------------
As documentation says (http://php.net/manual/en/datetime.createfromformat.php):

If format does not contain the character ! then portions of the generated time which are not specified in format will be set to the current system time.

While in php >= 7.3.0 it's not the case anymore. Date fractions are filled, but time are zeroed.

➜ docker run -v $(pwd):/app --rm php:7.2-cli php /app/dt.php
int(1551845370)
string(29) "2019-03-06T04:09:30.000+00:00"

➜ docker run -v $(pwd):/app --rm php:7.3-cli php /app/dt.php
int(1551845374)
string(29) "2019-03-06T00:00:00.000+00:00"

Test script:
---------------
<?php

$now = \DateTime::createFromFormat('u', 0);

var_dump(time(), $now->format(\DateTime::RFC3339_EXTENDED));
