mmm perfect application to use an external RTC like DS1307.

Melanie did an excellent code example http://www.melabs.com/resources/samp...ted/MN1307.txt

this should be enough to start. The only things you'll have to add is the alarm... BUT as i know, there's some RTC with built-in alarm. Maybe somebody here can suggest you one.

Steve has already mentioned the DS1307

As your request for a code example was your very first post, you should start HERE

if you don't want to use an RTC, and had searched the Forum you would have ended up THERE

There are many other RTC examples, do some searching...
