this is because the init scripts use some fancy options to set colors. This seems to be done by stty, which won't work on a fake tty like the one used by cron. I don't know why you're restarting openntpd from cron every hour though, as it's a daemon that keeps running all the time. Restarting it has no use. Well, I think I had added it because it seemed that after a long uptime it wasn't working properly... dunno. I've disabled it now.
