I mentioned a few weeks back that it was odd that the evenings were getting longer and the mornings barely budging. I am now in a postion to provide the answer.
Some years ago a schoolboy howler of an exam answer was reported in the papers. The question demanded an explanation of why days were longer in summer and shorter in winter and the kid wrote: "When things get hot they expand and when they get cold they contract."
Like everbody else I laughed at this but ... the kid must have been right! The nights are cold and it takes a bit for the sun to warm things up and so the mornings are not expanding (i.e. getting earlier) as quickly as the evenings are getting later when the day is cooling down and so contracting. Problem solved. Forget all this nonsense about orbits and precession.
