Bug #51457 [Opn->Bgs]: gmdate interpretation

Edit report at http://bugs.php.net/bug.php?id=51457&edit=1 ID: 51457 Updated by: aharvey@php.net Reported by: mobile at bingeman dot org dot uk Summary: gmdate interpretation -Status: Open +Status: Bogus Type: Bug Package: Date/time related Operating System: linux PHP Version: 5.3.2 New Comment: Since you're in the UK, and your computer/server is hence probably set to Europe/London as a time zone, this is likely due to daylight saving time. For example, with 2010-04-01, strtotime() will be returning 12:00 am on the 1st of April in your local time zone, but as the UK is now GMT+1, gmdate() interprets that as being 11:00 pm on the previous day (which it is in GMT), hence you get the result of 31-03-2010.

Any date displayed using gmdate from and including 29/03/2010 and upto 04/04/2010, possibly further, is being displayed as the stored date LESS 1 day. Example DB table shows 2010-03-30 echo gmdate("d-m-Y", strtotime("$test1")); interpretates the same information as 29-03-2010. Am I missing the point or is there something wrong?
