Correctly. 
This is the inconsistency.

Format "c" is a ISO 8601 date and have colon, and DateTimeInterface:ISO8601 = "Y-m-d\TH:i:sO" but does not have colon...

That's right, 'O' does not have a colon while the timezone offset in 'c' does.

What bug are you reporting?

Description:
------------
In https://www.php.net/manual/en/class.datetime.php we have 

const string DateTimeInterface::ISO8601 = "Y-m-d\TH:i:sO" ;

The format 0 = Difference to Greenwich time (GMT) without colon between hours and minutes 	Example: +0200 (https://www.php.net/manual/en/datetime.format.php)

But the format('c') full date/time define:
c 	ISO 8601 date (added in PHP 5) 	2004-02-12T15:19:21+00:00

We can to see that the format is inconsistency, format "c" is not equal to Y-m-d\TH:i:sO it would be 2004-02-12T15:19:21+0000
