Hi,

There are loads of 24 hour timer/ clocks out there, including this forum.

Finding one with 6 digits and set point timers perhaps not so many, but something like this one could be readily adapted.

Just depends if you want to do anything other than build it like a kit ..?

Also look in the Arduino Playground for ready made timer/clock

Not that difficult put together/adapt your own using a micro, ds1307 and lcd
