Changing the time twice a year was first established by the Summer Time Act of 1916, after a campaign by builder William Willett, so that evenings have more daylight and mornings have fewer daylight hours. It’s been changed a couple of times since then, notably during WW II when ‘Double’ summer time was introduced, 1941 to 1945 when Britain was GMT+2. Between 1968 and 1971 the clocks stayed at GMT+1 but statistics showed an increase in traffic accidents during the morning hours but a substantial decrease in the evening so UK reverted back to GMT/BST changes each year. Beginning at one o’clock, Greenwich mean time, in the morning of the last Sunday in March and ending at one o’clock, Greenwich mean time, in the morning of the last Sunday in October.
I hate it, it’s not natural, messes with my body clock, I’ve only just begun to get it into my head that in UK I can’t go shopping late evening, as most shops close after 17:00 hrs.
A very enjoyable day trip on a nice sunny day (rare this last few months) while visiting my Daughter in Somerset.
We visited deepest darkest Wales and decided some exploring near Abergavenny was in order. There was an ulterior motive; a search for a house I lived in for a short time when knee high to a Grasshopper.
I had a memory of a river, Dam and heading away from Abergavenny, but no names other than it was near a place called Forest Coal Pit. The river was in a valley on the right hand side going towards the dam. Out came the O.S map of the area and after following a few very ! narrow roads, found it and now know the name of the river again – Grwyne Fawr.
An update – these could be hard Calcite crystals given their luminosity: reading a couple of technical papers (see link below) on the geological structure of Jebel Shams would seem to indicate this.
I have limited knowledge on the subject of geology.
