Clock return values

[Jontenoy]

Hi, I wish to have a 24 hour clock and notify a pin (make it high) during a preprogrammed interval . Anybody know of some suitable software ?

The search phrase "arduino irrigation timer" or day timer for your particular application will turn up many examples.

Do you really need an Arduino when you can get this for a few bucks ?
