Be aware that perl5 already will support a 64-bit time_t if it is
compiled as a 64 bit application. This is because time_t is defined as
long, and on LP64 platforms (the majority of 64 bit platforms are I
think), long becomes 64 bit when apps are compiled to be 64 bit:
$ cat t.c
#include <sys/types.h>
int main() { printf("time_t is %d bits\n", sizeof(time_t) * 8); }
$ cc -o t t.c
$ file t
t: ELF 32-bit MSB executable SPARC Version 1, dynamically
linked, not stripped
$ ./t
time_t is 32 bits
$ cc -o t t.c -xarch=v9
$ file t
t: ELF 64-bit MSB executable SPARCV9 Version 1, dynamically
linked, not stripped
$ ./t
time_t is 64 bits
