I did exactly the same thing. There is a piece of code floating on the net that implements time functions. You just need to provide tick increment every second. Do not have the code handy.. just google for it. It does add a bit of code space ~3 kB, and some funcs have internal static strings that will eat into your ram. As I recall the whole board was drawing 15 uA and most of it was going into the 3.3V regulator output ;-). Should provide 7.7 years of operation from 1000 mA battery. Sergei
