For longer intervals a 32 bit global is incremented every second.
clock-avr.h contains the specific setup code for each mcu.
The 1284p can use TIMER2 with external 32768 Hz clock at 125 ticks/sec.
The 1284p routine also uses TIMER2 to sleep a variable number of seconds.
It calls this routine to adjust the clock after a sleep.
