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:
