From: rolosworld at gmail dot com Operating system: gentoo PHP version: 5.2.5 PHP Bug Type: Date/time related Bug description: Incorrect time_t for x86-64
Description: ------------ Linux localhost 2.6.22-hardened-r8 #2 SMP Tue Dec 4 21:57:04 CST 2007 x86_64 Dual-Core AMD Opteron(tm) Processor 1210 AuthenticAMD GNU/Linux Im having problems with the date functions, seems the time_t used by php is 32bit, but the time_t of the system is 64bit. PHP uses 64bit integers so php is compiled for 64bit. To check the system time_t: #include <cstdio> #include <ctime> int main () { printf ("Size of time_t %d.\n", sizeof(time_t)); return 0; } g++ t.cpp -o t OUTPUT: Size of time_t 8. g++ -m32 t.cpp -o t OUTPUT: Size of time_t 4. Reproduce code: --------------- <?php echo "size: ",PHP_INT_SIZE,"\n"; echo "max: ",PHP_INT_MAX,"\n"; echo "mktime1: ",mktime(21,14,7,1,18,2038),"\n"; echo "mktime1: ",mktime(21,14,8,1,18,2038),"\n"; ?> Expected result: ---------------- size: 8 max: 9223372036854775807 mktime1: 2147483647 mktime2: 2147483648 Actual result: -------------- size: 8 max: 9223372036854775807 mktime1: 2147483647 mktime2: -- Edit bug report at http://bugs.php.net/?id=44296&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=44296&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=44296&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=44296&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=44296&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=44296&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=44296&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=44296&r=needscript Try newer version: http://bugs.php.net/fix.php?id=44296&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=44296&r=support Expected behavior: http://bugs.php.net/fix.php?id=44296&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=44296&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=44296&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=44296&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=44296&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=44296&r=dst IIS Stability: http://bugs.php.net/fix.php?id=44296&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=44296&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=44296&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=44296&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=44296&r=mysqlcfg
