Description:
------------
`\DateTime::createFromFormat('Y-m-d\TH:i:sP', '2015-06-09T14:00:00-07:00')` works but `\DateTime::createFromFormat('Y-m-d\TH:i:s.vP', '2015-06-09T14:00:00.000-07:00')` doesnt.

`var_dump(\DateTime::getLastErrors())` outputs `array(4) { ["warning_count"]=> int(0) ["warnings"]=> array(0) { } ["error_count"]=> int(2) ["errors"]=> array(2) { [26]=> string(35) "The format separator does not match" [27]=> string(13) "Trailing data" } }`

It is being triggered by the `v` option which should be supported.

Test script:
---------------
\DateTime::createFromFormat('Y-m-d\TH:i:s.vP', '2015-06-09T14:00:00.000-07:00');
var_dump(\DateTime::getLastErrors());

Looks like this got missed out when we added 'v' to formatting. However, this has recently been added to timelib (the library behind the functionality). Parsing 'v' should make it into PHP 7.3.

This should be changed into a Documentation bug if v is not present in 7.2 - docs say it was added in PHP 7.0.0 currently

Hey guys, please update the docs accordingly.
I was trying stuff like a mad man and thought I was slowly going crazy.

I made this test script, that shows that 'v' does NOT work in 7.1 or 7.2 even tho the documentation states that it was added in 7.0.

Test: https://3v4l.org/qUpGv
Docs: https://www.php.net/manual/en/function.date.php

I will have to work around this problem, because the JavaScript Date.toISOString() method returns a string exactly like in the test script, would have been nice to be able to just use it like that.

Thanks for all the hard work.

This really should be removed from the documentation; it's very confusing.

*Parsing* v is indeed supported as of PHP 7.3.0, and the
changelog[1] has apparently been fixed in the meantime.

*Formatting* v is actually supported as of PHP 7.0.0[2].

It is only confusing, if you assume that *parsing* and
*formatting* support the same specifiers, what you should not.
