Accurate Sleep Mode

[skimask]

Hi, Apart from NAP and SLEEP which use the watchdog as the counter, is there a way of incrementing a counter based on the xtal clock and using as little power as possible ? I am trying to maintain a reasonable accurate clock timer, whilts in low poer mode. thnks

32khz xtal on TMR1 with a prescale kicking an interrupt which increments a counter?
We don't know which PIC you got.
