Doc #68569 [NEW]: Datetime microseconds precision loss

From: jenson at axis dot com Operating system: Debian PHP version: 5.4.35 Package: Date/time related Bug Type: Documentation Problem Bug description:Datetime microseconds precision loss Description: ------------ --- From manual page: http://www.php.net/class.datetime --- When creating a DateTime object from ISO string (ie 2014-11-28T12:39:36.257642Z) the microseconds returned by format('u') differ from microseconds in the timestring for certain strings. Test script: --------------- $t = "2014-11-28T12:39:36.257642Z"; $d = new DateTime($t); echo "Input: " . $t . "\n"; echo "Microseconds from datetime: ". $d->format('u'); // ends in 1 Expected result: ---------------- $t = "2014-11-28T12:39:36.257641Z"; $d = new DateTime($t); echo "Input: " . $t . "\n"; echo "Microseconds from datetime: ". $d->format('u'); // Correct -- Edit bug report at https://bugs.php.net/bug.php?id=68569&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68569&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68569&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68569&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68569&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68569&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68569&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68569&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68569&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68569&r=support Expected behavior: https://bugs.php.net/fix.php?id=68569&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68569&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68569&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68569&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68569&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68569&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68569&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68569&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68569&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68569&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68569&r=mysqlcfg
