At least on openbsd that happens via the nmea(4) line discipline. Open
the TTY, call the TIOCSETD ioctl(2), and the kernel does the
timestamping for you. I don't think that's been implemented anywhere
else.

It doesn't appear to be present in any of the other BSDs, otherwise I
would've ported it to openbsd long ago.
