Bug #71802 [NEW]: strtotime parses "13:01 PM" as 16:01

From: php at richardneill dot org Operating system: Linux PHP version: 5.6.19 Package: Date/time related Bug Type: Bug Bug description:strtotime parses "13:01 PM" as 16:01 Description: ------------ The time expression "13:01 P.M." is technically malformed (it's tautologous), but people are still likely to use it sometimes. PHP mis-converts it, turning 13 into 16 !. (In comparison, the Unix date command rejects it) Test script: --------------- PHP: <? echo date ("Y-m-d H:i:s", strtotime("13:01 P.M.")); #result: 2016-03-11 16:01:00 #expected: 2016-03-11 13:01:00 echo date ("Y-m-d H:i:s", strtotime("12:01 P.M.")); #result: 2016-03-11 12:01:00 #correct ?> Shell: $ date -d '13:01 P.M.'; date: invalid date ‘13:01 P.M.’ $ date -d '12:01 P.M.'; Fri Mar 11 12:01:00 GMT 2016 Expected result: ---------------- PHP shouldn't be off-by-3. -- Edit bug report at https://bugs.php.net/bug.php?id=71802&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71802&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71802&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71802&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71802&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71802&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71802&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71802&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71802&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71802&r=support Expected behavior: https://bugs.php.net/fix.php?id=71802&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71802&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71802&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71802&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71802&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71802&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71802&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71802&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71802&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71802&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71802&r=mysqlcfg
