Thanks for the low clock speed info Jack, I'm not familiar with changing the boards.txt file and fuses (yet!). It's programmed with an FTDI-USB cable.
I've gone back to the standard 16MHz speed for simplicity as the board will only be running at full power briefly while the interval is being set up.
When the board is running the timer with 1-second sleeps and a direct 5V power supply it's averaging about 1.7mA. The LCD takes about 1.2mA so the Arduino is averaging 500uA.
