#50744 [NEW]: Missing days in Sept 1752

From: nuke at psu dot edu Operating system: All? PHP version: 5.3SVN-2010-01-14 (snap) PHP Bug Type: Date/time related Bug description: Missing days in Sept 1752 Description: ------------ In ext/date/lib/interval.c around line 58, there should be a flag to test for years before, say, 1753, and throw a warning for people to use the Calendar functions, assuming those functions are doing it correctly. I'd check the Calendar functions today, esp. GregoriantoJD, except that it's already 3am here. Besides, that'd be a different test. Here's one webpage about the issue I found in 1752: http://www.genealogytoday.com/columns/everyday/030902.html Reproduce code: --------------- $one = new DateTime("1752-09-02 00:00:00"); $two = new DateTime("1752-09-14 00:00:00"); $diff = $one->diff($two); echo $diff->days."=1"; Expected result: ---------------- 1=1 Actual result: -------------- 12=1 -- Edit bug report at http://bugs.php.net/?id=50744&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50744&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50744&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50744&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50744&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50744&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50744&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50744&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50744&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50744&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50744&r=support Expected behavior: http://bugs.php.net/fix.php?id=50744&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50744&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50744&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50744&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50744&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50744&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50744&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50744&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50744&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50744&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50744&r=mysqlcfg
