Pgp is much happier if gettimeofday returns something for
the usec field. Here's a version that tries to do that.
#include <sys/types.h>
#include <time.h>
#include <sys/time.h>
#include <unistd.h>
#include <stdlib.h>
#include <string.h>
#include <fcntl.h>
static int
ms(void)
{
char b[20];
static int f = -1;
/* XXX - should use native plan9 syscalls herein */
memset(b, 0, sizeof(b));
if (f < 0) {
f = open("/dev/msec", O_RDONLY);
fcntl(f, FD_CLOEXEC, 1);
}
if (f >= 0) {
lseek(f, 0, 0);
read(f, b, sizeof(b));
}
return atol(b) % 1000;
}
int
gettimeofday(struct timeval *tp, struct timezone *tzp)
{
tp->tv_sec = time(0);
tp->tv_usec = ms() * 1000;
if(tzp) {
tzp->tz_minuteswest = 240;
tzp->tz_dsttime = 1;
}
return 0;
}
