Long Delays - Is there a valid way?

[Darrel Taylor]

If you need to cut something, and you have a Sharp knife in your hand. Why look for a Dull one to do the job?

The Elapsed Timer Demo compiles to 149 words (without the daily task). So it easily fits into a 12F629 if you wanted. If you need the accuracy, use a crystal. If you don't, use the internal oscillator.

After a year, it should only be off by about 24 minutes or less.

I can't imagine how the thing could be inaccurately slow for a while, then become inaccurately fast for a while. But I don't really know.

The oscillator will run faster or slower depending on the ambient temperature. So indoor applications can be more stable that outdoor ones.
