It's due to the fact that the routines I use for the length of the day aren't accurate to that degree. I wanted to remove the facility because of it, but lots of people asked for it to stay.

I have accurate routines if you want them, but how about rounding to the nearest minute and dropping the seconds? Sunrise/set is all a bit hit and miss anyway as it depends on elevation, local horizons, atmospheric pressure, temperature, humidity, grandma's maiden name etc.

The problem with that is that the difference in day length would then be limited to a very small range of figures; typically zero or one for a lot of the year. I did wonder about rounding to a number of seconds, though; 5 or 10 perhaps should do it.

I thought it timely to mention that the summer / winter solstice occurs in about 6 hours time. Cumulus will probably report that Saturday 22nd will be a few seconds longer than Friday 21st June.

This is not a bug folks. ;)
Cheers,
