    Clock Accuracy Over Long Periods


      I need to create a timeout that occurs 60 days after power up.  I realize that I cannot do this accurately but that is OK.  I would like to know the possible error.  The crystal I use (24 MHz) has a spec of 30ppm, the Creator IDE list the ILO tolerance of +-2%, which is correct?
