#2606 closed defect (fixed)

alarm() uses seconds watchdog and thus is affected by clock changes

Description

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().
