Anyone have advice for a working clock?  I have an RTC module, but I don't know how to program it to remember time.
What sort of RTC might that be?

At http://fjkraan.home.xs4all.nl/digaud/arduino/index.html is an example of a timer clock based on the DS1307 switching a relay on time and light conditions. For each time comparison I convert the time from the RTC to seconds (on this day).

The code structure could be better, but I ran into RAM limitations, so I left it as is. It is good enough for me ;-)
