 alarm() uses _Watchdog_Insert_seconds() and thus is affected by clock
 changes, e.g. via _TOD_Set(). This is wrong. The POSIX documentation is
 not that clear since it talks only about "realtime seconds". However, the
 FreeBSD implementation uses the uptime. This is also in line with the
 RTEMS ualarm() and nanosleep().
