sleep_start is in seconds, right? I do not see how it could explain
1hr10 difference... Please do not apply this.

OTOH try this code (in userspace, run as root). It did strange thigs
to my time, and it is unrelated to swsusp. (But it does similar weird
things with interrupts).

pavel@amd:~$ cat misc/latency.c
void
main(void)
{
        int i;
        iopl(3);
        while (1) {
                asm volatile("cli");
                //              for (i=0; i<20000000; i++)
                for (i=0; i<1000000000; i++)
                        asm volatile("");
                asm volatile("sti");
                sleep(1);
        }
}
