$datetime = new DateTime('0000-00-00 00:00:00');
$date_string = $datetime->format('Y-m-d H:i:s');//-0001-11-30 00:00:00
date gets turned from 0000-00-00 00:00:00 to -0001-11-30 00:00:00
this is obviously wrong, why does this happen, how to fix it?
Should at least return false.

It’s sort of correct by definition:
Take the (hypothetical) 1st of Jan in the year 0, subtract a month -> 1st of Dec in the year -1.
Subtract a day -> 30th of Nov in the year -1
Alternatively, they could have chosen to fix up the day first, then it’d go like:
1 Jan minus 1d -> 31st of Dec -0001, minus 1mo -> 30th of Nov -0001
The formatter obviously does the bound check to only produce valid dates. (For some definition of “valid”)
