Description: ------------ For lots of negative-year dates, the day of the week is reported as "Unknown". Sundays (0th day) are okay. The most modern date affected appears to be -0007-10- 01. The test script below runs through each day in the year -10 as an example. Test script: --------------- <?php $utc = new DateTimeZone('UTC'); $period = new DatePeriod( new DateTime('-0010-01-01', $utc), new DateInterval('P1D'), new DateTime('-0009-01-01', $utc) ); foreach ($period as $date) { if ($date->format('D') === 'Unknown') { echo $date->format('Y-m-d D') . PHP_EOL; } } ?> Expected result: ---------------- No output is expected. Actual result: -------------- -0010-01-01 Unknown -0010-01-02 Unknown -0010-01-03 Unknown -0010-01-04 Unknown -0010-01-05 Unknown -0010-02-01 Unknown -0010-02-02 Unknown -0010-03-01 Unknown -0010-03-02 Unknown -0010-05-01 Unknown -0010-05-02 Unknown -0010-05-03 Unknown -0010-05-04 Unknown -0010-06-01 Unknown -0010-08-01 Unknown -0010-08-02 Unknown -0010-08-03 Unknown -0010-10-01 Unknown -0010-10-02 Unknown -0010-10-03 Unknown -0010-10-04 Unknown -0010-10-05 Unknown -0010-11-01 Unknown -0010-11-02 Unknown -- Edit bug report at https://bugs.php.net/bug.php?id=55687&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55687&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55687&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55687&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55687&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55687&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55687&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55687&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55687&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55687&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55687&r=support Expected behavior: https://bugs.php.net/fix.php?id=55687&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55687&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55687&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55687&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55687&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55687&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55687&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55687&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55687&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55687&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55687&r=mysqlcfg
