a program to facilitate setting a clock in sync with linux?

[John G. Heim]

I actually already have a system such as you describe. Here is a link to 
a tgz file:

http://www.iavit.org/~john/debian/oclock.tgz

This script says the current time, just the hour and minute, in a fairly 
nice  artificial voice. Personally, I run it once an hour from crontab. 
It requires aplay which,on debian, is part of the alsa-utils package. 
The key thing to this is actually the sound files. You can look at the 
script but it's opretty much just a one liner with the aplay command 
taking the output from the date command. In fact, you could do something 
similar with the output from the date command being fed to espeak.

Installation:

1. Cd to a suitable directory for the script. /usr/local/bin is a good 
choice:

cd /usr/local/bin

2, Un-tar the file:

tar -zxf oclock.tgz

3. Call the script from crontab:

0 * * * * root /usr/local/bin/oclock/oclock
