[ntp:questions] Audible signal generator ("BBC pips")?

As the Raspberry Pi I am currently using as a NTP box has 
an audio output available, I am wondering if this otherwise
unused output (on a dedicated NTP box) could be used to
generate BBC style pips or other audible time signals?

As I am probably not the first one to have that idea:
Is there software for Linux that does this? Playing 
a sound file is easy. Playing it in sync with ntpd 
is a lot harder.
