Bug #75745 [NEW]: DateTime::createFromFormat "u" specifier not interpreted correctly

From: daverandom Operating system: Any PHP version: 7.1.12 Package: Date/time related Bug Type: Bug Bug description:DateTime::createFromFormat "u" specifier not interpreted correctly Description: ------------ The "u" specifier is documented as "microseconds" but is interpreted as "fraction of a second". While this is not the correct behaviour, it is potentially a desirable behaviour, specifically one might expect to be able to interpret a date like 12:13:14.42 as having a fractional part. I propose adding an "f" specifier (currently unused) which retains this old behaviour, and fixing "u" to work as documented. Test script: --------------- echo DateTime::createFromFormat('u', '42')->format('u'); Expected result: ---------------- 000042 Actual result: -------------- 420000 -- Edit bug report at https://bugs.php.net/bug.php?id=75745&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75745&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75745&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75745&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75745&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75745&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75745&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75745&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75745&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75745&r=support Expected behavior: https://bugs.php.net/fix.php?id=75745&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75745&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75745&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75745&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75745&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75745&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75745&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75745&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75745&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75745&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75745&r=mysqlcfg
