This is rtc, a kernel module for /dev/rtc device support.
Some apps such as VMware for Linux would be happy with it. The code was originally written by Vladimir N. Silyaev. Note: It _includes_ Linux ioctl support, but basically it's FreeBSD native stuff. I'm importing this into emulators category for convevience' sake. Check it out.
