Melanie-Thanks again for the fast responses.

I'll try your suggestion counting WDT events.

Max time in sleep mode is closer to 2 hours, not 5, and the timer/clock will be reset at least once a day so accumulative time errors will not exist past the end of say 16 hours of continous operation.

I was hoping you would suggest some of your code from the Olympic Timer project. I saw something that might work at this link http://www.picbasic.co.uk/forum/showthread.php?t=603

What do you think?
