 I've seen Fire Alarm, Security, Intercom,
Telephones and Bells integrated together on
one system; but, I've never seen the clocks
integrated with any of them (except that the
Master Clock: runs the Bells which ring over
the PA Speakers, can change the Telephone
configurations and can change the Intercom
configurations multiple times per day).

 TTYL.
