Check out Dallas Semiconductor for some nice serial clocks. I am messing
around with a DS1302. I like it.

the stamp? Something that has a clock pulse of 1Hz, and has a SPI interface
would be great. I am looking to make a 10 minute timer, and the time has to
be accurate. A chip sold at digikey would be great, cause I'll probably be
making an order there soon.
