Fall back

I liked the idea of the clocks changing and as I remember them in the Autum/Winter, the term 'fall back'

I thought I could look at the idea of using clocks and clock parts possible as a visual vehicle for the the theme. I don't know if this is too obvious and how far I could go with this idea but I thought it was worth exploring it.

In the European Union, Summer Time begins and ends at 1:00 a.m. Universal Time (Greenwich Mean Time). It begins the last Sunday in March and ends the last Sunday in October. In the EU, all time zones change at the same moment.

Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn.^[1] Modern DST was first proposed in 1895 by George Vernon Hudson.^[2] Many countries have used it since then; details vary by location and change occasionally.

What changes does clock change bring?
Towards the end of the year, as the earth's axial tilt moves the northern hemisphere away from the sun, winter sets in. At the same time, summer arrives in the southern hemisphere.
In the UK the warming effect of the sun, now at a lower angle in the sky, is weakened. Also the sun starts setting earlier so that in the depths of winter the nights are anything up to 19 hours long.
On clear winter nights heat escapes from the ground for longer than it does in the summer, so allowing temperatures to fall further and increasing the chance of frost and fog.
During the other half of the year, the opposite happens. The earth's northern hemisphere tilts towards the sun, bringing summer to the north and plunging the southern hemisphere into winter.
Then, for those of us in the northern hemisphere, days begin to get longer and the nights shorter.
