Edit report at https://bugs.php.net/bug.php?id=77745&edit=1 ID: 77745 Updated by: requinix@php.net Reported by: dnkonev at yandex dot ru Summary: Unexpected result DateTime::createFromFormat -Status: Open +Status: Not a bug Type: Bug Package: Date/time related Operating System: Ubuntu 18.04.1 LTS PHP Version: 7.1.27 Block user comment: N Private report: N New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php 'Y' expects the "full numeric representation of a year", which is probably but not necessarily going to be four digits. If you give it 29 it will assume 0029, and if you give it 10 it will assume 0010. If you have two digits and want a year between 1970-2069 then use 'y' instead.
